Questions
How big is the Speed joystick PCB?
It measures 126.6 × 72.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Speed joystick use?
83 parts, built around the TXS0108EPW, SK6812 and JS5208. 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 Speed joystick KiCad files?
From the owhite/ebike_speedo repository on GitHub, at the commit this page was made from: the board is joystick_speedo_kicad/speed_joystick.kicad_pcb and its schematic 7_segment_kicad/ebike_LED.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Speed joystick 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).
