The Centromere Plus keyboard is a split wireless ergonomic keyboard that can be built with both standard Cherry MX style switches and low profile Kailh Choc switches. It is fully programmable and customizeable.
This new version adds 3 keys on the inside of each board, for a total of 6 extra keys without increasing the size of the keyboard.
It comes with a USB receiver module that allows you to customize the keymaps and layers via the popular QMK framework for mechanical keyboards. Having a receiver allows you to minimize wireless latency compared to a board with Bluetooth, and allows for extended battery life. Program the keyboard and change the keymap with a single command by downloading the QMK fork from the Southpaw Design Github.
The kit includes the wireless receiver, PCBs,plates of your choice, and through-hole diodes. All keyboards will be pre-programmed with default keymaps, so you just need to solder the diodes and switches to get started with your new Centromere Plus. It features an on-off switch to save power and prevent errant keypresses when traveling with the board. Each half is powered by a CR2032 coin cell battery. One coin cell battery will last a couple of months of daily use.
Two plate options are available, black or white.
The two outer keys in the thumb cluster can be used as 2 1u keys as shown, or you can use 1 2u key. In that configuration, a 2u Cherry PCB-mounted stabilizer can be used
