Errata
rev 1.1 : RJ45 connector is round the wrong way rev 1.1a : Relay outputs silkscreen is labelled incorrectly. NC is actually on the side closest to the SD card connector, not the voltage regulator side which is NO.

Questions
How big is the ACNode Shield PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ACNode Shield use?
15 parts, built around the SRD-05VDC-SL-C, WS2812B and PN2222A. 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.
Where can I download the ACNode Shield KiCad files?
From the londonhackspace/acnode-cl repository on GitHub, at the commit this page was made from: the board is hardware/ACNode-Shield/ACNode-Shield.kicad_pcb and its schematic hardware/acnode-reader-direct/acnode-reader-direct.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ACNode Shield design in my own project?
Its repository states no licence, so its author keeps all rights: ask londonhackspace before reusing the design.
