Questions
How big is the SHMod24 RF IR Bridge PCB?
It measures 46 × 46 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SHMod24 RF IR Bridge use?
42 parts, built around the MT3608 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 SHMod24 RF IR Bridge KiCad files?
From the LeoDJ/SHMod24-IR_RF_Bridge repository on GitHub, at the commit this page was made from: the board is SHMod24_RF_IR_Bridge.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SHMod24 RF IR Bridge design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
