Excellent for university projects
Used this for my final year project. Reliable and easy to program with STM32CubeIDE.

Good value
Solid hardware for the price. Wish the pinout diagram was clearer in the box, but online docs help.

Perfect for embedded learning
Great board for getting started with STM32. The display works out of the box and the pinout is standard.

Display had issues
Board works fine but the OLED had a dead pixel. Still usable for testing logic.
Q: Is the SWD interface available for debugging?
A: Yes, SWDIO and SWCLK pins are broken out for debugging purposes.
Q: What library works best with the display?
A: We recommend the U8g2 library for OLED support on this module.
Q: Which IDE is compatible with this board?
A: Keil MDK, STM32CubeIDE, and PlatformIO are all supported.
Q: Does it support 5V logic levels?
A: No, this is a 3.3V logic board. Use level shifters for 5V peripherals.
Q: Can I power this via USB only?
A: Yes, the Micro USB port provides sufficient power for normal operation.
