The Corne v4.1 is the latest version of an opensource keyboard created by foostan and is one of, if not, the most popular, ergo split keyboards available today. This is a wired keyboard and uses the ever popular RP2040 microcontroller. This is built into the keyboard itself. This makes this keyboard very slim, portable, and flexible. While at this time we only offer one variant, you are able to change up to 4 of the switches to rotary encoders, OLED displays, or just remove the added switches and use it as a much cleaner version of the famous v2/3 variant. This keyboard uses MX spacing, choc hotswap sockets, and full RGB support.
