A board for the left over keycaps that I don't use
Few of my keyboards use all of the keys in a typical keyset. I have many left over Shift, Enter, Backspace, etc... keycaps. This is somewhat related to the
I-S-hOle.
Mostly the larger than 1u keycaps. They fit nicely in a 5x5 size square grid. 95mm square. Gerber files on
git.
PCB mount switches and
PCB mount 2u Cherry stabilizers.
The matrix is 4x5, 4 columns and 5 rows. There is a
JSON file for use with

Cols F4 F5 F6 F7
Rows D4 C6 D7 E6 B4
Powered by a
Pro Micro. The USB connector comes out the side of the board. There was no way to position it coming out the top due to the odd spacing of the switches. The unused pins are broken out to pads. There are pads for a 5.2mm surface mount tactile switch connected to RESET.
There are also pads for a
TRRS jack. I have not built it, but this should work as a split keyboard.
Like the
Gherkin I use a second PCB as the bottom. M2 spacers and screws hold the two together.
