# Toy PCB Brain Transplant Guide
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
Instead of building a whole new board, desolder the original MCU from the
|
||||||
|
toy's PCB and replace it with a breakout connector wired to the XIAO
|
||||||
|
nRF52840. The original PCB keeps doing everything it's good at (power,
|
||||||
|
buttons, motor, speaker routing) — you just swap the brain.
|
||||||
|
|
||||||
|
## What You Need
|
||||||
|
|
||||||
|

|
||||||
|
|------|-------|-------|
|
||||||
|
| SOP-16 solder-down DIP adapter | $2 | Logical Systems PA-SOF-D420-16, or generic SOIC-16→DIP breakout |
|
||||||
|
| Seeed XIAO nRF52840 | $10 | The new brain |
|
||||||
|
| IS25LP128F (SPI flash) | $2 | Audio storage (solder to a small perfboard with the XIAO) |
|
||||||

|
||||||
|
| Solder, flux, solder wick | — | For desoldering and rework |
|
||||||
|

|
||||||
|
|
||||||
|
**Total added cost: ~$15** (and you reuse 90% of the original toy)
|
||||||
|
|
||||||
|
|
||||||
|
## Step 1: Document the Original Board
|
||||||
|
|
||||||
|
Before desoldering anything:
|
||||||
|
|
||||||
|
1. **Photograph both sides** of the PCB in good light
|
||||||
|
2. **Identify the MCU** — look for markings like TRSF1602A, chip-on-board
|
||||||
|
(black blob), or other SOP-8/SOP-16 packages
|
||||||
|
3. **Note the pin 1 indicator** — dot, notch, or beveled corner
|
||||||
|
4. **Count pins** — this guide assumes SOP-16, but adapt for SOP-8
|
||||||
|
5. **Trace visible connections** by eye:
|
||||||
|
- Which pins have fat traces? → probably power (VCC/GND)
|
||||||
|
- Which pins connect to the speaker? → audio output
|
||||||
|
- Which pins go to the motor area? → motor drive
|
||||||
|
- Which pins go to buttons? → GPIO inputs
|
||||||
|
|
||||||
|
|
||||||
|
## Step 2: Desolder the Original MCU
|
||||||
|
|
||||||
|
**Hot air method (recommended):**
|
||||||
|
1. Apply flux to all pins
|
||||||
|
2. Set hot air to ~350°C, low airflow
|
||||||
|
3. Heat evenly around the chip until solder reflows
|
||||||
|
4. Lift chip with tweezers
|
||||||
|
5. Clean pads with wick and flux
|
||||||
|
|
||||||
|
**Soldering iron method:**
|
||||||
|
1. Apply flux generously
|
||||||
|
2. Add fresh leaded solder to all pins (lower melting point helps)
|
||||||
|
3. Drag iron back and forth across pins on each side
|
||||||
|
4. Use solder wick to remove excess
|
||||||
|
5. Gently pry chip up while heating one side, then the other
|
||||||
|
6. Clean pads with wick
|
||||||
|
|
||||||
|
**If it's a chip-on-board (black blob):**
|
||||||
|
Unfortunately, these can't be desoldered. You'll need to cut the traces
|
||||||
|
instead and jumper to the XIAO. Identify the traces leading to the blob
|
||||||
|
and cut them with an X-acto knife, then solder wires directly to the
|
||||||
|
button/speaker/motor pads on the board.
|
||||||
|
|
||||||
|
|
||||||
|
## Step 3: Solder the SOP-16 Breakout Adapter
|
||||||
|
|
||||||
|
1. Place the SOP-16 → DIP adapter on the now-empty pads
|
||||||
|
2. Align pin 1 with the original pin 1 marking
|
||||||
|
3. Tack-solder two corner pins
|
||||||
|
4. Check alignment under magnification
|
||||||
|
5. Solder remaining pins
|
||||||
|
6. Now you have 16 through-hole pins you can plug jumper wires into
|
||||||
|
|
||||||
|
|
||||||
|
## Step 4: Reverse-Engineer the Pinout
|
||||||
|
|
||||||
|
This is the detective work. You need to figure out what the original
|
||||||
|
MCU was connected to on each pin.
|
||||||
|
|
||||||
|
### 4a: Power pins (multimeter, board OFF)
|
||||||
|
|
||||||
|
Set multimeter to continuity/beep mode.
|
||||||
|
|
||||||
|
1. Touch one probe to the battery negative terminal (GND)
|
||||||
|
2. Touch the other probe to each of the 16 breakout pins
|
||||||
|
3. **Mark any pins that beep as GND**
|
||||||
|
4. Now touch one probe to battery positive (after the power switch)
|
||||||
|
5. Touch other probe to each remaining pin
|
||||||
|
6. **Mark any pins that beep as VCC**
|
||||||
|
|
||||||
|
Typical SOP-16 MCUs have 1-2 GND pins and 1-2 VCC pins.
|
||||||
|
|
||||||
|
|
||||||
|
### 4b: Speaker pins (visual trace + multimeter)
|
||||||
|
|
||||||
|
Follow the traces from the speaker solder pads back to the breakout.
|
||||||
|
Often the speaker connects through a small capacitor or resistor, then
|
||||||
|
to one or two MCU pins.
|
||||||
|
|
||||||
|
- **One speaker pin** = single-ended PWM audio (most common)
|
||||||
|
- **Two speaker pins** = bridge-tied-load (BTL) direct drive (no amp chip)
|
||||||
|
|
||||||
|
|
||||||
|
### 4c: Motor pin (visual trace)
|
||||||
|
|
||||||
|
Follow the motor wires. In cheap toys, the motor often connects to a
|
||||||
|
single transistor (TO-92 or SOT-23 package near the motor area). The
|
||||||
|
transistor's base connects (through a resistor) to an MCU pin.
|
||||||
|
|
||||||
|
If there's no transistor and the motor connects directly to an MCU pin
|
||||||
|
(rare but possible on very cheap toys), you'll need to add a MOSFET —
|
||||||
|
MCU pins can't drive motors directly.
|
||||||
|
|
||||||
|
|
||||||
|
### 4d: Button pins (multimeter, board OFF)
|
||||||
|
|
||||||
|
For each physical button on the toy:
|
||||||
|
1. Press the button while testing continuity between its pads
|
||||||
|
2. Trace one pad to GND (common) and the other to an MCU pin
|
||||||
|
3. Label that breakout pin as a button input
|
||||||
|
|
||||||
|
Most cheap toys wire buttons between the MCU pin and GND, relying on
|
||||||
|
the MCU's internal pull-up resistor — same as our design.
|
||||||
|
|
||||||
|
|
||||||
|
### 4e: Automated pin discovery (firmware)
|
||||||
|
|
||||||
|
Upload the pin_discovery sketch (included below) to the XIAO. Connect
|
||||||
|
each breakout pin one at a time to a XIAO GPIO and the sketch will
|
||||||
|
tell you what it sees:
|
||||||
|
- High/low/floating state
|
||||||
|
- Whether pressing a button changes it
|
||||||
|
- Whether it shows PWM activity when the toy was running
|
||||||
|
- Approximate voltage level
|
||||||
|
|
||||||
|
|
||||||
|
## Step 5: Create the Pin Map
|
||||||
|
|
||||||
|
Fill out a table like this for your specific toy:
|
||||||
|
|
||||||
|
| SOP-16 Pin | Connects To | XIAO Pin | Notes |
|
||||||
|
|------------|-------------|----------|-------|
|
||||||
|
| 1 | VCC | 3V3 | Power supply |
|
||||||
|
| 2 | GND | GND | Ground |
|
||||||
|
| 3 | Button 1 | D0 | Play/Pause (active LOW) |
|
||||||
|
| 4 | Button 2 | D1 | Next track |
|
||||||
|
| 5 | Button 3 | D2 | Motor on/off |
|
||||||
|
| 6 | Button 4 | D3 | Volume/speed |
|
||||||
|
| 7 | Speaker + | D10 | PWM audio output |
|
||||||
|
| 8 | Speaker - | GND | Or second PWM for BTL |
|
||||||
|
| 9 | Motor ctrl | D6 | Through transistor on board |
|
||||||
|
| 10 | NC | — | Not connected |
|
||||||
|
| 11-16 | ... | ... | (varies by toy) |
|
||||||
|
|
||||||
|
|
||||||
|
## Step 6: Wire It Up
|
||||||
|
|
||||||
|
1. Solder header pins to the XIAO if not already done
|
||||||
|
2. Solder the IS25LP128F flash chip to a small piece of perfboard
|
||||||
|
next to the XIAO (VCC, GND, and 4 SPI wires)
|
||||||
|
3. Run jumper wires from each SOP-16 breakout pin to the
|
||||||
|
corresponding XIAO pin per your pin map
|
||||||
|
4. Connect VCC breakout pin → XIAO 3V3 (to power the XIAO from toy batteries)
|
||||||
|
5. Connect GND breakout pin → XIAO GND
|
||||||
|
|
||||||
|
**IMPORTANT voltage check:** Before connecting power, measure the toy's
|
||||||
|
VCC with batteries installed. If it's 2×AA (3V) or 3×AA (4.5V), you
|
||||||
|
can connect directly to the XIAO's 3V3 pin (which accepts 1.7-3.6V on
|
||||||
|
the nRF52840). If the toy uses more than 3 batteries (>5V), you MUST
|
||||||
|
use the XIAO's 5V pin or add a regulator.
|
||||||
|
|
||||||
|
For 2×AA: Connect through the TPS61220 boost to get stable 3.3V,
|
||||||
|
then feed that to XIAO 3V3. Or if you're fine with the limited voltage
|
||||||
|
range, connect the battery VCC directly to XIAO 3V3 — the nRF52840
|
||||||
|
runs down to 1.7V, but the IS25LP128F needs 2.3V minimum, so you'll
|
||||||
|
lose the bottom of the battery capacity.
|
||||||
|
|
||||||
|
|
||||||
|
## Step 7: Update the Firmware Pin Mapping
|
||||||
|
|
||||||
|
In baby_mobile_v2.ino, update the pin definitions to match your wiring:
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
// Adjust these to match YOUR toy's pin map
|
||||||
|
#define PIN_AUDIO_PWM D10 // connected to speaker trace
|
||||||
|
#define PIN_AMP_SD -1 // set to -1 if toy has no separate amp
|
||||||
|
#define PIN_MOTOR_PWM D6 // connected to motor transistor base
|
||||||
|
#define PIN_BTN1 D0 // play/pause button
|
||||||
|
#define PIN_BTN2 D1 // next
|
||||||
|
#define PIN_BTN3 D2 // motor toggle
|
||||||
|
#define PIN_BTN4 D3 // fourth button
|
||||||
|
// ... set unused buttons to -1
|
||||||
|
```
|
||||||
|
|
||||||
|
If the toy's original circuit drives the speaker directly from the MCU
|
||||||
|
(no amp chip), the XIAO's PWM output through the RC filter should work
|
||||||
|
similarly. The original PWM was likely at a higher carrier frequency
|
||||||
|
(the TRSF1602A runs at up to 13MHz), but 8kHz audio content will
|
||||||
|
sound the same.
|
||||||
|
|
||||||
|
|
||||||
|
## Common Toy PCB Patterns
|
||||||
|
|
||||||
|
### Pattern A: Direct-drive speaker (most common in cheap toys)
|
||||||
|
```
|
||||||
|
MCU pin → small cap (100nF-1µF) → Speaker+
|
||||||
|
Speaker- → GND
|
||||||
|
```
|
||||||
|
The MCU generates PWM, the cap blocks DC. No amplifier. Maximum volume
|
||||||
|
is limited by the MCU's output current (~20mA). This works fine with
|
||||||
|
the XIAO — just set the PWM pin and skip the PAM8302A entirely.
|
||||||
|
|
||||||
|
### Pattern B: Transistor amplifier
|
||||||
|
```
|
||||||
|
MCU pin → resistor (1K-10K) → transistor base
|
||||||
|
collector → Speaker+
|
||||||
|
emitter → GND
|
||||||
|
Speaker- → VCC
|
||||||
|
```
|
||||||
|
Again, the XIAO's PWM drives this directly. The transistor provides
|
||||||
|
current amplification.
|
||||||
|
|
||||||
|
### Pattern C: Dedicated amp IC (higher-end toys)
|
||||||
|
```
|
||||||
|
MCU pin → coupling cap → amp IC input
|
||||||
|
amp IC output → Speaker ±
|
||||||
|
```
|
||||||
|
Here you're feeding the amp's input from the XIAO PWM through the
|
||||||
|
existing coupling cap. Should work as-is. If there's a shutdown pin
|
||||||
|
on the amp, trace it back to the MCU and control it from the XIAO.
|
||||||
|
|
||||||
|
### Motor drive patterns:
|
||||||
|
```
|
||||||
|
Common: MCU pin → resistor → NPN base → motor → VCC
|
||||||
|
emitter → GND
|
||||||
|
diode across motor
|
||||||
|
|
||||||
|
Simple: MCU pin → motor → VCC (tiny motors only, <20mA)
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
**No sound:** Check speaker connections. Measure voltage on the audio pin
|
||||||
|
with a multimeter while playing — you should see ~1.5V average. If 0V,
|
||||||
|
wrong pin. If VCC, the pin is driving high but not PWMing.
|
||||||
|
|
||||||
|
**Distorted sound:** The RC filter values may need adjustment. Try
|
||||||
|
increasing R2 or C7 to lower the cutoff frequency. Also check that
|
||||||
|
analogWriteResolution(8) is set in setup().
|
||||||
|
|
||||||
|
**Motor doesn't spin:** The XIAO pin may not source enough current to
|
||||||
|
drive the transistor. Check if the base resistor is reasonable (1K-10K).
|
||||||
|
If the original design was a darlington or MOSFET, the XIAO should
|
||||||
|
drive it fine.
|
||||||
|
|
||||||
|
**Buttons don't work:** Verify the button wires go to GND when pressed.
|
||||||
|
Some toys use a resistor ladder (all buttons on one ADC pin with
|
||||||
|
different resistor values) — this requires reading analogRead() instead
|
||||||
|
of digitalRead(). The pin_discovery sketch will detect this.
|
||||||
|
|
||||||
|
**Board doesn't power up:** The original MCU may have been pulling
|
||||||
|
certain pins to specific states that other components depend on. Check
|
||||||
|
if any traces from the MCU footprint go to enable pins on regulators
|
||||||
|
or other ICs on the board.

# Baby Mobile Audio Board v2 — Design Document
|
|
||||||
|
|
||||||
## Overview
|
|
||||||
|
|
||||||
Drop-in replacement for baby crib mobile electronics. Custom audio from
|

SPI flash, DC motor control, 8 buttons, and long runtime on 2×AA batteries.
|
|
||||||
No programmer needed — upload audio via USB drag-and-drop or Bluetooth.

||||||
BAT54S TPS61220

|
||||||
BAT54S MCP1700 L ─── L1(4.7µH)
|
|
||||||
```
|
|
||||||
|
|
||||||
**Why this is safe:** The Schottky diodes only pass current in one direction.
|
|
||||||
When USB provides 3.3V via the LDO, the boost converter stops switching and
|
|
||||||
the battery diode is reverse-biased. Zero current flows into the batteries
|
|
||||||
regardless of chemistry (alkaline, NiMH, lithium).
|
|
||||||
|
|
||||||
**Diode drop:** BAT54S drops ~0.25V. TPS61220 accepts inputs down to 0.7V.
|
|
||||||
Depleted 2×AA = 1.8V → boost sees 1.55V → still operational.

## Module Options (Soldering Difficulty)
|
|
||||||
|
|
||||||
The schematic is designed around the MDBT50Q module, but the firmware
|
|
||||||
works on any nRF52840 board. Here are your options from easiest to hardest:
|
|
||||||
|
|
||||||
| Module | ~Cost | USB-C | Bootloader | Soldering |
|
|
||||||
|-----------------------------|-------|-------|------------|------------------|
|
|
||||||
| **Seeed XIAO nRF52840** | $10 | Yes | UF2 preloaded | **Through-hole headers** — solder like any DIP. Has castellated pads too. |
|
|
||||||
| **Adafruit Feather nRF52840** | $25 | Yes | UF2 preloaded | Through-hole headers |
|
|
||||||
| **SparkFun Pro nRF52840** | $20 | Yes | UF2 preloaded | Through-hole headers |
|
|
||||||
| **Ebyte E73-2G4M08S1C** | $3 | No | None | Castellated edge pads — hand-solderable with regular iron |
|
|
||||||
| **MDBT50Q-P1MV2 (Raytac)** | $6 | No | None | SMD pads — needs reflow or hot air |
|
|
||||||
|
|
||||||
**Recommended for beginners: Seeed XIAO nRF52840.** It plugs into standard
|
|
||||||
2.54mm headers like an Arduino Nano. USB-C and UF2 bootloader are built in,
|
|
||||||
so you never need a programmer. Just drag-and-drop firmware and audio files.
|
|
||||||
|
|
||||||
**If using a XIAO or Feather:** you can skip the TPS61220 boost converter,
|
|
||||||
MCP1700 LDO, USB-C connector, and CC resistors from the BOM. The dev board
|
|
||||||
handles all of that. Feed the boost converter's 3.3V output to the board's
|
|
||||||
3V3 pin. Total BOM drops to ~$15 including the XIAO.
|
|
||||||
|
|
||||||
**If using MDBT50Q or E73:** you need the full schematic as designed. The
|
|
||||||
E73 is the budget option — castellated pads are solderable with flux, a
|
|
||||||
fine tip, and patience. Pre-tin both the pads and the board footprint,
|
|
||||||
then tack one corner and reflow the rest.
|
|
||||||
|
|
||||||
|
|
||||||
## User Experience
|
|
||||||
|
|
||||||
### Upload Audio (USB)
|
|
||||||
1. Plug USB-C cable into board
|
|
||||||
2. Board appears as USB mass storage drive
|
|
||||||
3. Drag .wav or .mp3 files onto drive
|
|
||||||
4. Eject and unplug — music ready to play
|
|
||||||
|
|
||||||
### Upload Audio (Bluetooth)
|
|
||||||
1. Open Web Bluetooth page on phone (no app install)
|
|
||||||
2. Connect to "BabyMobile" device
|
|
||||||
3. Select audio files → transfer
|
|
||||||
4. ~15 min for 30 minutes of audio at BLE speeds
|
|
||||||
|
|
||||||
### Update Firmware
|
|
||||||
1. Double-tap reset button (or hold BTN1+BTN2 on power-on)
|
|
||||||
2. Board appears as UF2 drive
|
|
||||||
3. Drag .uf2 firmware file onto drive
|
|
||||||
4. Board reboots with new firmware
|
|
||||||
|
|
||||||
### No-Programmer Setup
|
|
||||||
The MDBT50Q ships with the nRF52840 bootloader ROM. Flash the Adafruit
|
|
||||||
nRF52 UF2 bootloader once via SWD (J4 header) using any $3 CMSIS-DAP
|
|
||||||
probe, J-Link, or even a Raspberry Pi. After that, all future updates
|
|
||||||
are drag-and-drop over USB. The SWD header is only needed once.

# Ordering & Assembly Guide
|
||||||
|
|
||||||
|
## JLCPCB Order Settings
|
||||||
|
|
||||||
|
Upload `baby-mobile-panel.kicad_pcb` gerbers with these options:
|

|
||||||
|
| **Castellated Holes** | **Yes** (required for adapters) |
|

|
| **V-Score** | **Yes** (break between carrier and adapters) |
|
||||||
|
| Quantity | 5 (minimum) |
|
||||||
|
| **Estimated Cost** | **~$8 for 5 panels** |
|
||||||
|
|
||||||
|
If ordering JLC assembly (SMT), upload `carrier_bom_jlc.csv`.
|
||||||
|
Otherwise, hand-solder the carrier components yourself — everything
|
||||||
|
is 0805 or larger except the TPS61220 (SC-70-5, fine-pitch but doable
|
||||||
|
with flux and a fine tip).

## Breakaway Adapter BOM
|
||||||
|
|
||||||
|
The adapters are **passive PCBs** — no components except one JST SH
|
||||||
|
connector each. Buy the connector that matches your adapter:
|
||||||
|
|
||||||
|
| Adapter | JST SH Pins | LCSC | ~Cost |
|
||||||
|
|---|---|---|---|
|
||||||

|
||||||
|
| SOP-16 narrow | 10-pin | C160404 | $0.30 |
|
||||||
|
| SOP-16 wide | 10-pin | C160404 | $0.30 |
|
||||||
|
|
||||||
|
You only need one adapter per toy — snap off the right one.
|
||||||
|
|
||||||
|
|
||||||
|
## Assembly Order
|
||||||
|
|
||||||
|
### 1. Carrier board (do this first, test before connecting to toy)
|
||||||
|
|
||||||
|
1. **Solder U1 (TPS61220)** — align pin 1 dot. Tin one pad, place
|
||||||
|
chip, reflow that pad, then solder remaining 4 pins.
|
||||||
|
2. **Solder L1, C1, C2** — boost converter circuit. Apply 2×AA
|
||||||
|
battery voltage to VBAT/GND test points. Measure 3V3 output —
|
||||||
|
should read 3.30V ±0.1V.
|
||||||
|
3. **Solder U2 (IS25LP128F)** — align pin 1 dot. Same technique as U1.
|
||||||
|
4. **Solder C3, R2** — flash decoupling and CS pullup.
|
||||||
|
5. **Solder R1, C5** — audio RC filter.
|
||||||
|
6. **Solder J1 (JST SH)** — align pin 1 mark.
|
||||||
|
7. **Solder J2, J3** — XIAO female headers.
|
||||||
|
8. **Plug in XIAO** — USB-C faces the left edge marked on silk.
|
||||||
|
9. **Test** — upload pin_discovery.ino, verify serial output.
|
||||||
|
|
||||||
|
### 2. Adapter board
|
||||||
|
|
||||||
|
1. **Snap off** the adapter matching your toy's MCU package.
|
||||||
|
2. **Solder JST connector** to adapter's top surface.
|
||||||
|
3. **Desolder** original MCU from toy PCB (hot air or iron + flux).
|
||||||
|
4. **Place adapter** in empty footprint, pin 1 aligned.
|
||||||
|
5. **Solder castellated edges** — the half-holes sit on the SOP pads.
|
||||||
|
Apply flux, touch with iron, solder wicks into the half-hole.
|
||||||
|
6. **Plug JST cable** from adapter into carrier J1.
|
||||||
|
|
||||||
|
### 3. Map and wire
|
||||||
|
|
||||||
|
1. Upload **pin_discovery.ino** to XIAO.
|
||||||
|
2. Use multimeter + the serial tool to identify each SOP pin's function.
|
||||||
|
3. Create your pin map (see BRAIN_TRANSPLANT.md).
|
||||||
|
4. Update **baby_mobile_v2.ino** pin definitions.
|
||||||
|
5. Upload final firmware.
|
||||||
|
6. Upload audio via USB mass storage.
|
||||||
|
|
||||||
|
|
||||||
|
## Silkscreen Guide
|
||||||
|
|
||||||
|
All polarized components have pin 1 dots (●) on the silkscreen:
|
||||||
|
- **U1 (TPS61220):** dot near pin 1 (VIN)
|
||||||
|
- **U2 (IS25LP128F):** dot near pin 1 (~CS)
|
||||||
|
- **J1 (JST SH):** dot near pin 1 (VBAT)
|
||||||
|
- **Each adapter:** dot near SOP pin 1
|
||||||
|
|
||||||
|
The XIAO outline shows the board rectangle with a USB-C bump
|
||||||
|
on the left edge. Pin labels (D0-D10, 3V3, GND, 5V) are printed
|
||||||
|
next to each header hole.

|
* Upload this to the XIAO nRF52840, then connect one breakout pin
|
||||||
|
* at a time to the PROBE_PIN. Open Serial Monitor at 115200 baud.
|
||||||
|
*
|
||||||
|
* The tool will tell you:
|
||||||
|
* - Resting voltage (VCC, GND, floating, pulled up/down)
|
||||||
|
* - Whether it responds to button presses
|
||||||
|
* - Whether it looks like an analog resistor ladder
|
||||||
|
* - Suggested function (power, button, output, NC)
|
||||||
|
*
|
||||||
|
* Workflow:
|
||||||
|
* 1. Desolder original MCU, solder SOP-16 breakout adapter
|
||||||
|
* 2. Install batteries in toy
|
||||||
|
* 3. Connect XIAO GND to toy GND (battery negative)
|
||||||
|
* 4. For each breakout pin, connect it to PROBE_PIN with a jumper
|
||||||
|
* 5. Type the pin number in Serial Monitor and press Enter
|
||||||
|
* 6. Follow prompts (press buttons when asked, etc.)
|
||||||
|
* 7. Tool builds a pin map as you go
