A 94 key ergonomic,split keyboard. Its powered by 2X Raspberry pico and linked with two 5 pin D sub connectors. It uses tht components.
The reset switches, 5 pin D sub connectors and raspberry pico's goes on the reverse side of the Pcb's.

PWM1 to PWM 5 controls LED's ( ON/OFF) based by the active layer, and also caps lock and scroll lock active.
Those and the electrical diagram can be found here: https://github.com/Supermagnum/Europe-ergo/blob/main/Europe-ergo-PCB/schema/Europe-ergo.pdf The right side has identical outputs for PWM.
Cherry MX switches fit the PCB'S.
