Following the naming convention (MikeTypeson, Clacky Chan), Stephan (Rollercole) Møller shared Leonardo KeycapRio – a tented unibody MX keyboard. The custom PCB uses squiggles to allow bending without breaking it.
Just finished my latest board, the Leonardo KeycapRio. He is the slickest looking board I have made so far – Stephan.
Features
- 30 keys, 5x3+1-ish monoblock split
- MX switches, hotswap
- single flexible PCB
- RP2040 Pro Micro controller
- 3D printed tented base
- ZigMkay firmware
No screws, no glue – the PCB is press-fit onto the tenting base.
