Description

Capactive sensing (EC) pcb for Le Chiffre keyboard

README

Le Capybara Keyboard

Capacitive sensing (aka Topre) keyboard in Le Chiffre layout

Status

Fully tested

Manufacturing

Plates have m2 threaded holes for securing the plate and switches to the PCB. DIY tapping is not difficult if your plate manufacturer does not offer tapping services.

Recommended plate material is 1.2mm steel. Plate files are in the expected physical dimensions. No kerf adjustments have been applied. The dxf files have been used successfully with SendCutSend and LaserBoost. JLCPCB is not recommnded for the plates without further testing to adapt to their milling process.
