A simple PCB that repairs (and improves!) a circa mid-1990s Brio wooden train electronic light and sound signal crossing. I inherited one. The PCB was completely shot. So I measured the board, made a Kicad design, had it fabbed and reconnected it to the toy.

Questions
How big is the Brio hack PCB?
It measures 28 × 16.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Brio hack use?
36 parts, built around the PAM8302AADCR, W25Q32JVZPIQ and PTS810. 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 Brio hack KiCad files?
From the GyrocopterLLC/brio_hack repository on GitHub, at the commit this page was made from: the board is hardware/brio_hack.kicad_pcb and its schematic hardware/brio_hack.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Brio hack 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).
