By natural extension, once there were many shields designed for it, many other *boards* began to be developed that were compatible to leverage the extensive available shields. Today, many dev kits come with Uno headers to make it easy to work with them. Note: ZMK doesn't support boards with AVR 8-bit processors, such as the ATmega32U4, because Zephyrâ„¢ only supports 32-bit and 64-bit platforms. As a result, boards like the original Arduino Uno Rev3 itself are *not* supported by ZMK.
