Tom's 3x5 board

Overview

A keyboard built using ergogen etc. 36 keys wireless using the Seeed studio Xiao nRF52840 module. This keyboard project heavily borrows from a few similar projects

• triboard
• TOTEM

The main features of my board are:

• Split
• Wireless
• 36 keys: 5 columns x 3 rows + 3 thumb keys on each side
• Cherry MX switches with hotswap socket
• Uses the cheaper/smaller nordic mcu instead of nice nano
• The ergogen project generates two boards and cases (left and right)
  • The boards are not flippable as the battery charger pads on the mcu would not be reachable

Prerequisites

• node is setup to be run on the system
• For building cases: npm install @jscad/csg (this is a deprecated package so must be installed explicitly)

How to generate the boards

./build (watches files and rebuilds when source changes/)

or

./build once

How to generate the cases

./build cases

TODO

• Increase the heat set insert radius as it is set with CA glue insted of being melted in (when printing with SLA resin)
• Add a printed part that slots over the switch and fits into the case allowing it to be easily comtrolled
