angular-mk/angularmk-rgbThe AngularRGB is a, minimalistic, 40% keyboard that supports perkey RGB Lighting. We've noticed that there are no purchasing options for anyone interested in a rgb per key backlit keyboard, so we decided to create one.
AngularRGB is an open-source printed circuit board by angular-mk, from the angular-mk/angularmk-rgb repository on GitHub. It is a 4-layer board of 228.6 × 76.2 mm with 192 parts on 171 nets.
It is built around the ATMEGA32U4-MU, 74LVC2G34GW and AMS1117-3.3, with the USB6B1, WS2812 and BSS138 among its other parts. Its parts include 85 diodes, 43 switches, 29 capacitors, 9 resistors and 5 ICs. It belongs with the lEDs and displays and keyboards and input boards and the AVR (ATmega, ATtiny) and nRF52 and nRF5x boards of this library.

The PCB consists of a 4x12 matrix layed out as a COL to ROW diode configuration with a staggered design. Additionally, there are slots cut out on the board to provide the space for the WS2812B-Mini RGB LEDs that provide the lighting. There are also numerous protection features, such as ESD protections for both the data lines aswell as the power lines; fueses protecting the precious microcontroller in a case of short circuit; and many more.

It measures 228.6 × 76.2 mm and has 4 copper layers, 1.6 mm thick.
192 parts, built around the ATMEGA32U4-MU, 74LVC2G34GW, AMS1117-3.3 and USB6B1. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the angular-mk/angularmk-rgb repository on GitHub, at the commit this page was made from: the board is AngularRGB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask angular-mk before reusing the design.
