Build - MX-10

There are gerber files in the folders.

It uses 3mm tall machine pin headers to create space for 301230 battery. The holes in the PCB are enlarged to allow the headers to sit flush with the board.

For every switch there is a 1N4148 diode in a SOD123 package. Diodes are soldered where an LED would normally be located, as the board has no lighting of any sort. Although can diodes be soldered by hand, a hot-air gun definitely makes task easier.

I've attached some rubber feet as well to keep it from sliding around.

Few things to note:

• There is a battery disconnect switch and a reset switch
• Although many controllers are shipped with included pin headers, they are not to be used on this board.
• The pinout used is that of the NiceNano. If you use another board, leave the outermost pins unused. Refer to the RAW pin noted on the PCB.

Footnotes

1. Enables mounting MX-compatible switches using either through-hole soldering or the hot-swappable mount. Note that the switch will be "upside-down" when mounted in the socket, which may interfere with Cherry Profile keycaps. ↩

2. 18mm x 17mm spacing between switches. ↩ ↩²
