Overview
Driver is an open-source printed circuit board by augustt198, from the augustt198/flipdot repository on GitHub. It is a 2-layer board of 54.6 × 127 mm with 64 parts on 226 nets, routed with 2,216 tracks and 155 vias.
It is built around the MCP23017-E/SS, LF50ABDT-TR and LM7815CT. Its parts include 44 transistors, 9 ICs, 3 capacitors, 3 resistors and 3 connectors. It belongs with the lEDs and displays boards and the NXP (LPC, Kinetis, i.MX RT) boards of this library.

README
README.mdflipdot
A driver board for my 16x28 flipdot display (Luminator MAX 3000).
The connector folder has a PCB for converting the 3x32 connector on the display to a
2x32 connector (which is easier to find cables for).
The driver folder has the driver board. Ideally I would like a footprint that fits both a teensy
and an ESP2866.
Notes
- 15V is a good voltage to flip the dots, 50mA seems like enough current.

Questions
How big is the Driver PCB?
It measures 54.6 × 127 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Driver use?
64 parts, built around the MCP23017-E/SS, LF50ABDT-TR and LM7815CT. 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 Driver KiCad files?
From the augustt198/flipdot repository on GitHub, at the commit this page was made from: the board is driver/driver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Driver design in my own project?
Its repository states no licence, so its author keeps all rights: ask augustt198 before reusing the design.
