Reliable performance

Running a sensor data logger for weeks without any crashes. The 72MHz speed is sufficient for most tasks.

Great value for money

I bought five of these for my students. All of them were working out of the box. Highly recommended for education.

Good board, needs headers

The board itself is excellent. Just note that it does not come with pin headers soldered, so you need to do that yourself.
