Solid hardware
Pinout labeling on the silkscreen could be clearer, but the performance is stable for embedded tasks.

Perfect for learning ARM
This board is excellent for students transitioning from Arduino to ARM. The USB-C connection is reliable and the pinout is standard.
Q: Are the GPIO pins 5V tolerant?
A: Most GPIO pins are 3.3V logic. Please refer to the datasheet for specific 5V tolerant pins before connecting.
Q: Is there driver support for Linux?
A: Yes, it uses standard CDC ACM drivers which are natively supported by most Linux distributions.
Q: Does it come with an onboard debugger?
A: No, this board does not have an onboard debugger. You will need an external ST-Link programmer for debugging.
Q: Is this compatible with the Arduino IDE?
A: Yes, this board supports the Arduino IDE using the STM32duino bootloader package.
