Compact and powerful
Good board but pins are close together. Soldering skills needed for header installation. Performance is solid.

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