最高タイプ (SaikouType) ST110r2 Programmable Mechanical Keyboard Project

2018.05.21 | Yuki Rea

The SaikouType NKBM-ST110r2 is an open source, Cherry MX Mechanical keyboard project which uses a programmable Atmel AT90USB1286 Micro-controller in the form of a Teensy++ 2.0 development board. The goal of this project is to create a programmable keyboard that has advanced functionality without the need for a driver to make features work. Having a 100% through-hole design means that even soldering novices should be able to assemble their own keyboard with out difficulty. This keyboard was designed to reduce the total amount of components that one would need to source in order to complete assembly of a full keyboard. The NKBM-ST110r2 PCB fits existing Filco and other Costar case designs. Some supported cases include the Majestouch Convertible 2 with it's battery compartment and Rosewill RK9000. The ST110r2 has a universal layout so one PCB supports a wide range of standard and custom layouts. The ST110r2 can be programmed from scratch, with tmk_keyboard firmware, or with null_keyboard firmware.
