Questions
How big is the TurnSignal PCB?
It measures 61.4 × 19.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TurnSignal use?
27 parts, built around the FMMT491A, TL2230EEF100 and B2B-PH-K-S(LF)(SN). 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 TurnSignal KiCad files?
From the YingK8/Turn-Signal repository on GitHub, at the commit this page was made from: the board is TurnSignal.kicad_pcb and its schematic TurnSignal.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TurnSignal design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
