SPD40 Wireless Mechanical Keyboard

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. Both black and white top switch plates will be available. QMK firmware for remapping the keymaps is available here on Github.
