Questions
How big is the Remote PCB?
It measures 31.8 × 55.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Remote use?
23 parts, built around the ATTINY85-20SU, EVQ-Q2K02W and LTST-C170KFKT. 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 Remote KiCad files?
From the csl-taipeitech/85RF repository on GitHub, at the commit this page was made from: the board is kicad/remote.kicad_pcb and its schematic kicad/remote.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Remote design in my own project?
Its repository states no licence, so its author keeps all rights: ask csl-taipeitech before reusing the design.
