Questions
How big is the IR LED Controller PCB?
It measures 31.5 × 47.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the IR LED Controller use?
17 parts, built around the 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 IR LED Controller KiCad files?
From the wkkoes/IR-LED-Controller repository on GitHub, at the commit this page was made from: the board is IR_LED_Controller.kicad_pcb and its schematic IR_LED_Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IR LED Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask wkkoes before reusing the design.
