USB-C versus USB Micro connectors are turning into one of the holy wars of our time. Rather than be left on the wrong side of the divide [Stefan S] has come up with his own USB-C version of of an Arduino Pro Micro to avoid having to always find a different cable.

Home made Arduinos come in all shapes and sizes from the conventional to the adventurous, and from the pictures it seems that this one is firmly in the former camp. The USB-C is present in connector form alone as the device is only capable of talking at the much slower speed of the ATMEGA32U4 processor, but having the newer connector should at least make cabling more accessible.

This is one of the most practical Arduino clones we’ve ever seen, but one of our other favourites is also a bit impractical.
