CAN Bus Works Great
Tested the CAN interface with an OBD2 scanner and it communicated without issues. Great value for industrial prototyping.

Compact and Powerful
Fits perfectly in my enclosure. The STM32F103 is a classic chip and this board breaks out all the useful pins including CAN.

Solid Hardware
Good build quality and the pinout is standard. Would give 5 stars if the documentation was slightly more detailed for beginners.

Documentation Needed
Board works but wiki links were hard to find. Had to figure out some pin mappings myself. Hardware itself is reliable.
