Easy to program

USB bootloader works out of the box. Great for learning ARM development without needing a separate debugger.

5 FAQ

Q: What is the typical current consumption?

A: Typical run current is around 20mA at 84MHz, depending on peripheral usage and clock configuration.

Q: Is SWD header included on the board?

A: Yes, a 4-pin SWD header is available on the edge for external debugging and programming.

Q: Does it support Arduino IDE?

A: Yes, it is compatible with the Arduino IDE via the STM32duino package available in the board manager.

Q: Is 5V tolerant on GPIO pins?

A: No, GPIO is 3.3V logic only. Use level shifters if interfacing with 5V devices to prevent damage.

Q: How to enter DFU mode?

A: Hold the BOOT0 pin high during reset or power-on to enter the system memory bootloader mode.
