Perfect for RISC-V exploration
Works flawlessly with MounRiver Studio. The dual Type-C is very convenient for power and debugging simultaneously.

Documentation needs update
Hardware is good, but some example codes were outdated. Still recommended for the price point.

Good value but tiny pins
Board works great, but the pin headers are close together. Need steady hands for soldering if not pre-populated.
