Great value, tiny pins
Works well with Arduino IDE. Only downside is the pins are very close together, so soldering headers requires a steady hand.

Good board, learning curve
Hardware is solid. Took me some time to configure the board manager in the IDE. Would be nice to have a quick start guide included.

Easy to program
Plug and play via USB-C. No need for external programmers. The RISC-V architecture is fast enough for my home automation needs.
