I have two new keyboard designs I’ve made available on my site, a 40% wireless keyboard and a 60%. Both use receiver-base, QMK-programmable USB receivers for lower latency and better battery life than any DIY bluetooth keyboard solution.
Here are the links for the two keyboards:
Here’s a description for the SPD40. Both the SPD40 & SPD60 are very similar in terms of the way they operate, the SPD60 has more keys available. Both are relatively narrow 12U designs. The SPD40 requires MX switches and stabilizers, whereas the SPD60 has all keys widths <=2U so no stabilizers are necessary. This also makes the SPD60 compatible with MX, Choc V1, and Choc V2 switches.
Note: the ?/ and Function key of both keyboards can be swapped.
The SPD40 keyboard is a wireless, QMK-compatible keyboard that can use Cherry MX, or Kailh Low Profile Choc switches.
SPD40 was designed with ergonomics in mind. It is powered by a coin cell battery and is capable of lasting for 4-5 months before replacement. This keyboard is fully programmable. It features an ON/OFF switch for power saving purposes and will prevent errant keypresses if you choose to travel with it.
The SPD40 is a fully programmable 40 percent keyboard. These boards will come pre-programmed with the default keymaps, however you may download the QMK files and make whatever changes you can think of to customize the keyboard’s layout.
This keyboard is sold as a kit. You will receive a partially assembled keyboard with a black switch plate, diodes, a bottom protector plate, mounting hardware, and a pre-programmed micro-USB receiver. Simply choose the variety of switches you want to use, solder the switches and diodes, insert the batteries, and you have a working wireless keyboard.
Links to the QMK firmware for these keyboards can be found on the individual product pages.
I also have extras for the ergonomic Zygote keyboard, which is available here.
