Helps with university projects
Documentation is clear enough to get started. Supports CAN FD which was required for my automotive systems class. Very satisfied.

Good value
Board quality is high. Wish the pin headers were pre-soldered on this specific batch, but otherwise works perfectly for motor control.

Excellent STM32G4 option
Low power consumption modes work as expected. Great for battery-powered projects. The USB interface is reliable for debugging.

Fast shipping and great board
Compiles without errors using STM32CubeIDE. The voltage regulator is stable. Highly recommend for anyone moving from Arduino to STM32.

Perfect for prototypes
Used this board for a sensor hub project. The 170 MHz clock speed handles data logging smoothly. Pinout is standard and easy to breadboard.
Q: Can I use this for CAN bus applications?
A: Yes, the STM32G4 series supports CAN FD. This board breaks out the necessary pins for CAN transmission and reception.
Q: What is the recommended input voltage?
A: The logic voltage is 3.3V. You can supply 5V via the VIN pin or USB, which is regulated down to 3.3V for the MCU.
Q: Are the GPIO pins 5V tolerant?
A: Most GPIOs are 3.3V only. Please refer to the STM32G431CBT6 datasheet for specific pins marked as FT (5V tolerant).
Q: Is this compatible with STM32CubeIDE?
A: Yes, this board is fully supported by STM32CubeIDE. You can select the STM32G431CBT6 device when creating a new project.
Q: Does it have a built-in debugger?
A: No, this is a core board. You will need an external ST-Link V2 or V3 programmer to flash and debug the microcontroller.
