Great value
Very affordable compared to other development boards. The only downside is the pinout is a bit tight for larger jumper wires, but otherwise excellent.

Easy to program
Setup was straightforward. Drivers installed automatically on Windows 10. Great for learning embedded systems without breaking the bank.

Good board
Solid performance for the price. Documentation could be slightly better for beginners, but there are plenty of community resources available.
