About the Split-Keyboard PCB

Split-Keyboard is an open source PCB design by MadAvidCoder, published on GitHub under the MIT license. It is a 2-layer board measuring 294.2 × 112.3 mm, with 250 components from 22 distinct parts.

Other key parts include the DW01A, FS8205 and MT3608. By type, the board carries 64 capacitors, 56 diodes, 54 switches, 54 LEDs, 14 resistors and 6 ICs.

It belongs with the keyboards and power & battery designs in this gallery.

The case also features a cutout and location for the LiPo battery, so it can be easily secured. USB and charging access is via the edge above the thumb cluster.

For the thumb clusters, I have selected the Choc Louder Keycaps by kooziecup. The dimpled profile should make them more comfortable for the thumbs to rest on.
