README

This is a small beeper board, which is designed to find a lost model aircraft. It functions pretty much identical to the other commercial beepers. The main feature is the ability to deactivate the beeper using Betaflight.
Just activate the normal beeper function of Betaflight and pull the battery. Since the manual beep pattern is unique all other beep sources won't trigger the disarm.

Questions
How big is the Beeper PCB?
It measures 26.8 × 14.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Beeper use?
31 parts, built around the ATTINY13A-SSU and IRLML2502. 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 Beeper KiCad files?
From the koskev/betaflight-beeper repository on GitHub, at the commit this page was made from: the board is beeper/beeper.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Beeper 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).
