5 FAQ

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.

Q: What is the maximum current per IO pin?

A: Please consult the STM32F103RCT6 datasheet, but generally do not exceed 25mA per pin to ensure safety.
