It is wired same as a Planck, in reality as split planck with 2 PCB for 6x4 keys each, then connected by 2 wires 10 cores with a box that have the Teensy 2.0++ and goes out by USB connector.
I have made before another model hand wired based in same scheme of Planck, wiring is 4x12 in reality, but split too. With Teensy 2.0
My idea is that I can add easily leds to the box of microcontroller.
When testing (learning typing) I have found in some cases that I need info of what layout was active in an easy manner. But dont want decipher blink.
About leds,I need the info, by now the design is without leds.
