    A very nice board for those looking to try something in the 40% area. Very fun to build as well as it takes a bit of intricate soldering on the SMDs. Although I couldn’t get the reset button to fit in between the layers. It was constantly pushed in when I screwed the board together. So I removed it entirely, which isn’t a problem as long as you have a pair of tweezers to use when flashing.

    Regarding my previous review, Pete saw it and contacted me. He then sent all the correct parts so the keyboard is now flawless
