40% Mechanical keyboard PCB

Layout

In-switch LED support.
Individually addressible RGB underglow provided by 14 separate WS2812B LEDs.
USB Type-C connector on the left side.
Compatible with Cherry MX and ALPS switches.
Integrated 16MHz Atmega32u4 microcontroller for better QMK compatibility.
USB ESD protection circuit.
ICSP programming header just in case you try something a bit too extreme and need to unbrick it.
0805 SMD and through hole Diode/resistor compatibility for ease of assembly.
USB breakout for extra redundency.

KiCad 5 or above is needed to open this project. KiCad 4 or below won't work.
