turtleI think I've finished frogpad pcb design. It's based on Choc V1/V2 switches and has SK6812MINI-E RGB LEDs per key (20 total), plus 10 more for status indication. An nRF ProMicro used as the MCU with a deep mount. There are also 2 additional switches for stabilizing 2u keys. I’m not sure if this is the best approach, but I’ve seen some POS terminals use a similar approach.
