BoardPilotLaser module (KY-008) with ESP32
Supply 3.3-5 V
Bus GPIO
Pins and ESP32 wiring
| Pin | Role | ESP32 pin | Notes |
|---|---|---|---|
| S | Input (the ESP32 drives it) | D25 | HIGH = laser on. Never look into the beam |
| MID | Not wired to the ESP32 | — | Middle pin: not connected on many boards |
| GND | Ground | GND | Marked - on the board |
Suggested wiring for the 30-pin ESP32 DevKit, avoiding flash, input-only and strapping pins. BoardPilot checks it for you as you wire.
Starter code (Arduino)
void setup() { pinMode(25, OUTPUT); } // S
void loop() {
digitalWrite(25, HIGH);
delay(500);
digitalWrite(25, LOW);
delay(500);
