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.

Great for learning ARM
This board is perfect for students getting into embedded systems. The pinout is standard and it works flawlessly with STM32CubeIDE.

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