NEO-6M GPS with ESP32-C3-DevKitM-1

Wiring for the NEO-6M GPS module (GY-NEO6MV2) on the ESP32-C3-DevKitM-1 (ESP32-C3, 3.3 V logic), chosen with the same pin rules BoardPilot uses: default buses first, and no pins that are used for flash, USB, the debugger or booting.

Wiring

Check before you power it on

• Supply: 3.3 V from the 3V3 pin.

Test code (Arduino)

HardwareSerial gps(1);

void setup() {
  Serial.begin(115200);
  gps.begin(9600, SERIAL_8N1, 3, 10);  // RX, TX
}

void loop() {
  while (gps.available()) Serial.write(gps.read());  // NMEA sentences, e.g. $GPGGA
}

Arduino board: esp32:esp32:esp32c3. If uploading does not start, hold BOOT, press and release RST, then release BOOT.

Questions

Which ESP32-C3-DevKitM-1 pins do I use for the NEO-6M GPS?

VCC → 3V3, RX → 10, TX → 3, GND → GND.

Does the NEO-6M GPS work with the ESP32-C3-DevKitM-1 at 3.3 V?

Yes: the NEO-6M GPS runs at 3.3-5 V and the ESP32-C3-DevKitM-1 uses 3.3 V signals, so no level shifting is needed.
