Questions
How big is the IRstart - Remote PCB?
It measures 40 × 59.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the IRstart - Remote use?
56 parts, built around the AO3414A. 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 IRstart - Remote KiCad files?
From the OPRobots/IRStart repository on GitHub, at the commit this page was made from: the board is pcb_files/Remote/kicad_project/IRstart - Remote.kicad_pcb and its schematic pcb_files/Module/kicad_project/IRStart - Module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IRstart - Remote design in my own project?
Its repository publishes it under the GPL-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).
