Keyboard


image

A keyboard with 42 key Atreus layout. Uses Kailh Choc low profile switches with hot-swap sockets. Compatible with ProMicro type controllers, but designed to be used with Nice!Nano. Capable of n-key rollover. There is enough spacing between keys to fit all of the commonly available keycaps - transparent, flat and concave. PCB and case exports available in the github repo!

Sockets

The PCB has 1.5mm wide holes for mounting the controller socket. This allows soldering machine headers flush with the board. The nice!nano controller originally ships with low profile headers, which won’t fit the battery underneath the controller, if soldered in this manner. Therefore a pair of 3mm tall headers had to be separately ordered.

Led

In the nice!nano’s cover there are two openings for the LEDs. They can be filled with a dab of hot-glue before the print is removed form the bed to get a more diffused look …for science, you monster.
