Features:
- power rating: 12V x 15A = 180 W combined (as designed, but depends on actual components you will use)
- 3 channels (12V), each rated at 7A, having it's own fuse, 5V logic - tested on:
- ESP32 (devkit C) powered, with Wifi support - Web-Server control and remote firmware update
- MSGEQ7 spectrum analyzer connected to 3.5mm Audio Jack.
- USB-A port (0.8A) to power the remote audio-player.

Questions
How big is the LedStripDriver PCB?
It measures 110 × 91 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LedStripDriver use?
55 parts, built around the AO3400 and AO3400A. 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 LedStripDriver KiCad files?
From the ptabor/ledStrip repository on GitHub, at the commit this page was made from: the board is kicad/ledStripDriver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LedStripDriver design in my own project?
Its repository states no licence, so its author keeps all rights: ask ptabor before reusing the design.
