Questions
How big is the Esp32-beacon receiver PCB?
It measures 74.5 × 47 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32-beacon receiver use?
81 parts, built around the CH340C, ESP32-WROOM-32, TPS54331D and PCF8563T/5. 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 Esp32-beacon receiver KiCad files?
From the TheCacophonyProject/bluetooth-beacon-pcbs repository on GitHub, at the commit this page was made from: the board is esp32-beacon-receiver/esp32-beacon-receiver.kicad_pcb and its schematic esp32-beacon-receiver/esp32-beacon-receiver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32-beacon receiver 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).
