Compatible with all my shields

I tested this with several motor driver shields and sensor modules. The pin spacing is standard and everything fit perfectly. Highly recommended.

Works but headers not soldered

The board functions correctly, but I was surprised that the pin headers were not pre-soldered. I had to do that myself before using it.

Good board, driver installation needed

The hardware is solid, but make sure you install the CH340 drivers before connecting it to your computer. Once that was done, it worked flawlessly.

Perfect for learning electronics

This board works exactly like the original Arduino UNO. I used it for a school project and had no issues uploading sketches. Great value for the price.
