Best budget Cortex-M3 board
Using this for my university project. Low power consumption and plenty of memory for basic tasks.

Perfect for embedded learning
This board is exactly what I needed to start learning ARM development. Compiles quickly and pins are clearly labeled.

Good value but no headers
Great board functionality. Just note that you need to solder your own pin headers which wasn't clear to me initially.

Solid performance
Runs stable at 72MHz. Had to adjust voltage regulator jumper for USB power, but works well now.
Q: Does it come with a USB cable?
A: No, the board uses a Micro USB port for power but programming is typically done via SWD pins.
Q: Are the GPIO pins 5V tolerant?
A: No, the GPIO pins operate at 3.3V logic levels. Please use level shifters for 5V devices.
Q: Can I power this via the 5V pin?
A: Yes, you can supply 5V to the VIN pin, but ensure the voltage regulator jumper is set correctly.
Q: What debugger do you recommend?
A: We recommend using an ST-Link V2 programmer for the best SWD debugging experience.
Q: Is this compatible with the Arduino IDE?
A: Yes, this board supports the Arduino IDE using the STM32duino bootloader package.
