Good value but needs docs
Hardware is solid and price is competitive. However, the schematic provided could be more detailed for custom peripheral integration.

Perfect for embedded learning
This board is exactly what I needed for my university embedded systems course. The pinout is clearly labeled and it works seamlessly with STM32CubeIDE.

Fast shipping and works great
Arrived quickly and was well packaged. Uploaded the blink example immediately using an ST-Link debugger. No issues whatsoever.

Robust for industrial prototypes
We used this for a quick prototype in our control system. The 512KB flash is plenty for our logic and communication stacks. Very stable.

Excellent replacement board
Needed a replacement for a damaged core board in an existing project. This fit perfectly and all peripherals matched the original specifications.
Q: Does this come with an onboard debugger?
A: No, this is a minimal system board. You will need an external ST-Link or J-Link debugger to program it.
Q: What is the maximum current consumption?
A: Consumption varies by application, but the core typically draws around 30-40mA at 72MHz without peripherals active.
Q: How do I enter bootloader mode?
A: Set the BOOT0 jumper to high and BOOT1 to low, then reset the board to enter system memory bootloader mode.
Q: Is this board compatible with Keil MDK?
A: Yes, this board is fully compatible with Keil MDK, IAR EWARM, and STM32CubeIDE.
Q: Are the GPIO pins 5V tolerant?
A: No, the GPIO pins operate at 3.3V logic levels. Applying 5V directly may damage the microcontroller.
