Great value for money
Cheaper than comparable STM32 boards but performs well for basic tasks. Highly recommended.

Good but limited IO
The MCU is fast enough, but only 12 GPIOs can be limiting for larger projects. Still good for small nodes.

Excellent starter board
Works perfectly for learning embedded systems. The pinout is clear and documentation is helpful.
