Great Arduino Compatibility

I was able to upload my existing Arduino sketches without any modifications. The pinout is clearly labeled on the board which saves a lot of time during wiring.

Good Value but Docs Need Work

Hardware is solid and performance is good. However, the English documentation could be more detailed for advanced features. Still a good buy for the price.
