The 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.

It measures 62 × 19.3 mm and has 2 copper layers, 1.6 mm thick.
23 parts, built around the DHT11, WS2812 and BSS138. 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 GeorgK/SniffingTrinket repository on GitHub, at the commit this page was made from: the board is Hardware/Schematic/SniffingTrinket.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
