README
README.mdLeds are fun!
Created this project in 4h to drive a very long led strip i got at (scrapyard)[https://scrapyard.hackclub.com]. I didn't have any psu or mosfets to drive it, so I created this pcb.
Features
- has cool art
- has shiny mosfets
- has an esp32-f to control your leds wirelessly
- maybe works
- made by me

Questions
How big is the Leds PCB?
It measures 45.3 × 51.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Leds use?
16 parts, built around the IRF7201-HXY, CYA1040-33UH and WJ127-5.0-2P. 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 Leds KiCad files?
From the espcaa/led-system repository on GitHub, at the commit this page was made from: the board is kicad/leds.kicad_pcb and its schematic kicad/leds.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Leds design in my own project?
Its repository states no licence, so its author keeps all rights: ask espcaa before reusing the design.
