T. G. Marbach's JESK56 is a diodeless 56-key ortholinear keyboard, using a single RP2040-based microcontroller thanks to some fancy math and graph theory.
Moses Hoyt, from STHLM kb, shares his challenges, tips and tricks for overcoming the limitations of Pro Micro controllers in keyboard design.
Kazik is a cute 30% keyboard by monokēēbs – with versatile PCB, XIAO RP2040, and Japanese duplex matrix!
This post by wolfwood proposes a modification to the improved square keyboard matrix in order to support a low power wake-on-keypress mode, which has been a deficiency of this design until now.
The improved square matrix is actually a round-robin matrix handling the same number of switches – but with less diodes.
Let me introduce the square or round-robin matrix (aka Charlieplexing for keyboards) – a very tricky one promising 380 keys with a single Pro Micro.
There are two completely different keyboard matrices referred to as duplex matrix. Let's examine the Japanese one, which makes possible to handle 160-200 keys with a single Pro Micro.
