NEO-6M GPS with WeAct Black Pill STM32F411CE

Wiring for the NEO-6M GPS module (GY-NEO6MV2) on the WeAct Black Pill STM32F411CE (STM32F411CE, 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)

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:GenF4:pnum=BLACKPILL_F411CE,usb=CDCgen,upload_method=dfuMethod. To upload over USB, hold BOOT0, press and release NRST, then release BOOT0 (DFU mode). An ST-LINK on the SWD pins also works.

Questions

Which WeAct Black Pill STM32F411CE pins do I use for the NEO-6M GPS?

VCC → 3V3, RX → B12 (PB12), TX → B13 (PB13), GND → G.

Does the NEO-6M GPS work with the WeAct Black Pill STM32F411CE at 3.3 V?

Yes: the NEO-6M GPS runs at 3.3-5 V and the WeAct Black Pill STM32F411CE uses 3.3 V signals, so no level shifting is needed.
