A simple battery-powered LED grid a friend asked me to design for them, so they could put a vinyl decoration on top for conventions and stuff. The BOM included is for JLC, since it's what this prototype is designed for. Just plug a battery in and on your merry way :D
It's meant to be housed on a (yet to design) 3D printed case that will have a slot on the front for interchangeable vinyls to display as a con badge. It's powerful enough to blind you at short distance, and should be pretty good at dissipating heat. just make sure your battery is above 2500mAh and you'll be good for around 8 hours or so! :D

Questions
How big is the LED Grid PCB?
It measures 67 × 74 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LED Grid use?
279 parts. 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 LED Grid KiCad files?
From the dorythecat/LED-Grid repository on GitHub, at the commit this page was made from: the board is LED-grid.kicad_pcb and its schematic LED-grid.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LED Grid design in my own project?
Its repository publishes it under the AGPL-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).
