Perfect for industrial prototyping

The RS485 and CAN interfaces work flawlessly. The aluminum case keeps it cool during long tests. Sample code was easy to compile.

Great hardware, docs could be better

Board quality is excellent. Pinout is clear. Would give 5 stars if the wiki had more examples for the CAN bus configuration.

Solid STM32 board

Been using STM32 for years. This board saves time with built-in transceivers. No need for external modules. Verified working with Keil.

Good value for money

Works as described. USB cable included was a nice touch. Only minor issue was the pin headers were slightly loose on arrival.

Robust construction

Love the metal case. Protects the board well in messy lab environments. UART dual ports are very convenient for debugging.

5 FAQ

Q: Is this compatible with STM32CubeIDE?

A: Yes, fully compatible with STM32CubeIDE, Keil, and IAR.

Q: Does it come with a USB to TTL converter?

A: It features built-in interfaces, but programming requires an ST-Link or similar SWD debugger.

Q: Are the IO pins 5V tolerant?

A: Most GPIOs are 3.3V logic. Please check the datasheet for specific 5V tolerant pins before connecting.

Q: Can I power this via the USB port alone?

A: Yes, the board can be powered directly via the Micro USB connection.

Q: What is the maximum baud rate for UART?
