BoardPilotNEO-6M GPS with NUCLEO-F401RE
Wiring for the NEO-6M GPS module (GY-NEO6MV2) on the NUCLEO-F401RE (STM32F401RE, 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
| NEO-6M GPS pin | Role | NUCLEO-F401RE pin | Notes |
|---|---|---|---|
| VCC | Power | 3V3 | |
| RX | Input to the part | D2 (PA10) | |
| TX | Output from the part | D4 (PB5) | |
| GND | Ground | GND |
Check before you power it on
- Supply: 3.3 V from the 3V3 pin.
Test code (Arduino)
The Arduino core for this board numbers its pins differently from the chip names, so no code is shown here. Use the pin names from your core’s variant file.
Arduino board: STMicroelectronics:stm32:Nucleo_64:pnum=NUCLEO_F401RE. Plug the USB cable into the mini-USB port on the ST-LINK end. No button press is needed.
Questions
Which NUCLEO-F401RE pins do I use for the NEO-6M GPS?
VCC → 3V3, RX → D2 (PA10), TX → D4 (PB5), GND → GND.
Does the NEO-6M GPS work with the NUCLEO-F401RE at 3.3 V?
Yes: the NEO-6M GPS runs at 3.3-5 V and the NUCLEO-F401RE uses 3.3 V signals, so no level shifting is needed.
BoardPilot checks this wiring in 3D as you build it, and finds crossed or missing wires on the real board.
