Questions
How big is the Flipdot driver PCB?
It measures 67.5 × 49.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Flipdot driver use?
99 parts, built around the AX5201ESA, 74HC595, ULN2003A and USBLC6-2SC6. 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 Flipdot driver KiCad files?
From the xtompok/flipdot-driver repository on GitHub, at the commit this page was made from: the board is hw/flipdot-driver/flipdot-driver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Flipdot driver 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).
