Questions
How big is the Toslinkswitch PCB?
It measures 125.1 × 45.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Toslinkswitch use?
63 parts, built around the ATMEGA48A-AU, ATTINY85-20SU, SN74CBT3251D and PN2222A. 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 Toslinkswitch KiCad files?
From the psych0d0g/pcb_designs repository on GitHub, at the commit this page was made from: the board is toslink_switch/toslinkswitch.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Toslinkswitch design in my own project?
Its repository states no licence, so its author keeps all rights: ask psych0d0g before reusing the design.
