Overview
Aniboard is an open-source printed circuit board by cheyao, from the cheyao/aniboard repository on GitHub, published under the Zlib licence. It is a 2-layer board of 355 × 120 mm with 392 parts on 250 nets, routed with 2,172 tracks and 1,471 vias.
It is built around the ESP-12E, CH224K and AMS1117, with the AMS1117-3.3, SN74LVC1T45DBV and SK6812MINI-E among its other parts. Its parts include 180 diodes, 93 switches, 92 capacitors, 10 resistors and 6 ICs. It belongs with the keyboards and input boards and the ESP8266 and RP2040 boards of this library.

Case
The case v1 is fully parametric and made with OpenSCAD, allowed me to make a online case generator. Link after the YSWS ends.
V2 is made with freecad, and is of top mount style.
I chose to not add any engraving since it will look bad. I would want to print my case In school with ams and custom colored fillament when I buy some new fillament. (I need hq to print my case in white for the moment)

Please add this grant to my High Seas Digikey grant! <3
The stabs are 22.38 USD so going to transfer 5$ to HQ. Done, https://hcb.hackclub.com/hackpad/donations - Chengyin Yao aka Cyao
Uhh I think the TX are still over budget? Gonna figure something out. Found in budget TX! Gonna abuse new member discount lol.
The LCSC cart might seem to have excess of some components, it's either: minimal quanitity, or at the end I could spend 2.7$ more to save 6$ so why not

Questions
How big is the Aniboard PCB?
It measures 355 × 120 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Aniboard use?
392 parts, built around the ESP-12E, CH224K, AMS1117 and AMS1117-3.3. 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 Aniboard KiCad files?
From the cheyao/aniboard repository on GitHub, at the commit this page was made from: the board is PCB/aniboard.kicad_pcb and its schematic PCB/aniboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Aniboard design in my own project?
Its repository publishes it under the Zlib licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
