Idea

We wanted to create a pretty affordable, nice looking, and, most importantly, very DIY-friendly ergonomic wireless split keyboard with Gateron Low Profile switches.

Features

Low-profile, which will reduce strain on your beautiful hands;
Split. You can put the keyboard where it'll be comfortable exactly for you;
Pretty long battery life. 250mAh battery gives up to a month of usage without charging;
Wide availability and range of compatible keycaps;
Easily replaceable switches thanks to hot-swap sockets;
Budget-friendly, because:
- It uses relatively cheap and widely available Seeed Studio XIAO nRF52840 as MCU;
- It uses one PCB design for both halves of the keyboard;
- Everything except PCB's, components and hardware (screws, nuts) can be 3D printed.
Beginner-friendly, because:
- PCB is easy to solder;
- Cases are easy to print.
Wireless by design - no unnecessary wires, no unused connectors on the board;
Free in terms of hardware design. It's licensed under permissive CERN-OHL-P v2 license, which means:
- you are free to manufacture it yourself;
- you are free to sell your manufactured hardware for profit.
