Frequently asked questions
Will UNO shields fit this board?
Yes. It follows the UNO R3 header layout, so UNO-compatible shields should stack on it.
Does it need a driver on Windows?
Some clones use a CH340 USB-to-serial chip instead of the original USB interface, so you may need to install that chip's driver on Windows before the port appears.
