The TrueStrike42 by Choi Byungyoon (aka buyongyoonc/XYTEKK) is a column-staggered Hall-effect monoblock split keyboard designed to "maximize performance and minimize finger fatigue".

I always wanted a nice Rapid Trigger board after I heard about its clear advantage in rhythm games. There was no 40% HE board I could find, other than the great Lucca 58-HE by Maka8295, which was a split keyboard. I wanted a unibody split, so I decided to work on one myself – XYTEKK.

Features

• 42 keys (6x3+3)
• Hall-effect switches
• RP2040 devboard (Pro Micro pinout)
• OLED (optional)
• per-key RGB (optional)
• QMK/VIA firmware
