PCB designs

Perplexity

This is a split keyboard PCB with a lot of features, the main one being that it supports MX and Choc switches with the correct spacing for each. Unfortunately, I designed this without considering the minimum width between a breakaway part and the main board, which means that it can't be manufactured by a PCB fab.

I made a separate page with more information about the PCB.

Pocketkeeb

A 5*4 keyboard PCB for Kailh Choc switches that connects to another half using a ribbon cable. I designed a case to go along with it.

Absolem PCB

This is a PCB made for the Absolem keyboard. The Pro Micro or Proton-C joins two PCBs, and wires are used to connect the remaining connections between the two halves. The PCB supports MX, Alps, Choc, and Cherry ML switches.

Business card

This was an entry to the Keyboard Card Event contest, for information about it see my entry here.

Fractal2

Fractal2 is a 50% ortholinear keyboard that allows you to split the PCB in half and use it as a split keyboard, or to leave it as one piece and use it that way. It also supports moving the pro micro to the side of the keyboard to make it thinner.

FractalSP

FractalSP is a split 50% ortho PCB with a layout similar to the Keeb.io Nyquist keyboard, except that it has 1.25u thumb keys.

TRRS adapter

This is an adapter to allow you to use a USB-C port to connect the halves of a split keyboard PCB that uses PJ-320A TRRS connectors.

pmft

You probably don't need this, QMK's built in flasher works reliably.

PMFT is a tool to flash a hex file to a Pro Micro. It's based on a script from an Adafruit forum post. It makes it a lot easier to upload your keyboard firmware, and works far more reliably than using avrdude. You can get it at the project's GitHub page.
