About the KLOTZ split keyboard PCB

KLOTZ split keyboard is an open source PCB design by GEIGEIGEIST, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 120.6 × 85.5 mm, with 50 components from 11 distinct parts.

Other key parts include the nice!nano. By type, the board carries 18 switches, 17 diodes, 4 jumpers, 3 inductors, 3 resistors and 2 battery holders.

It belongs with the keyboards, iot & wireless and dev boards & breakouts designs in this gallery.

From the project

KLOTZ is 34 keys column-staggered split keyboard. It uses an encoder and three status LEDs on each side.

- upload the ZIP - sometimes the Gerber preview from JLCPCB can't display the PCB, even when the files are fine. In this case use this dimensions: 120.5 mm* 85.5 mm - PCB Thickness 1.6mm - 2 layers - PCB Qty as much as you like. But be aware, that you need 2 PCBs for one keyboard - PCB Color Black - No impedance control - Surface Finish HASL(with lead) if you want the easiest soldering experience or LeadFree HASL. - Remove Order Number Yes
