Solid hardware

Works well for my projects but note that it needs an external debugger like ST-Link V2 which is not included in the box.

Perfect for motor control

The G4 series handles PWM and motor control tasks very well. I used this for a drone controller project successfully.

Pinout unclear

The board functions correctly but the silk screen labeling on some pins could be clearer for beginners.

5 FAQ

Q: Which IDEs are supported?

A: This board is compatible with STM32CubeIDE, Keil MDK, IAR Embedded Workbench, and GCC-based toolchains.

Q: Does this board have a built-in debugger?

A: No, this core board does not include an onboard debugger. You will need an external ST-Link V2 or V3 programmer.

Q: What is the power consumption?

A: Power consumption depends on your application load. In run mode at 170 MHz, it typically draws around 30-40 mA.

Q: Is the bootloader pre-installed?

A: Yes, the standard STM32 system memory bootloader is pre-installed for UART or USB DFU programming.

Q: Are the GPIO pins 5V tolerant?

A: Yes, most GPIO pins on the STM32G474 are 5V tolerant, but please check the specific datasheet for pin constraints.
