Bus GPIO
Measures position, time
Pins and ESP32 wiring
| Pin | Role | ESP32 pin | Notes |
|---|---|---|---|
| VCC | Power | 3V3 | |
| GND | Ground | GND | |
| TXD | Output (the part drives it) | D25 | UART: the part sends data here. Connect to an ESP32 RX pin (9600 baud) |
| RXD | Input (the ESP32 drives it) | D26 | UART: the part receives data here. Connect to an ESP32 TX pin |
| PPS | Not wired to the ESP32 | — | One pulse per second after a fix, optional |
Suggested wiring for the 30-pin ESP32 DevKit, avoiding flash, input-only and strapping pins. BoardPilot checks it for you as you wire.
