I created this design because I wanted to upgrade my Sweep with the fancy nice!view displays. I decided to use the edge design from the Swoop and to make it compatible with Kailh hotswap sockets. This is a strictly wireless-only design, and is only compatible with ZMK / nice!nano. Only Choc v1 switches + Hotswap are supported!
Q: Why is this not just another Sweep? A: In order to support the nice!view display I had to use a switch matrix with diodes instead of the Sweep's direct pin design. This means that the firmwares are not interchangeable. I also wanted to use a different PCB shape which makes it incompatible with Sweep cases.
