Sharing a part for the Pervasive Displays EXT3-1 extension board, used with their EPDK kits to drive SPI e-paper panels (10-pin header, matches the 10-way rainbow bridging cable that ships with the kit). Couldn’t find it in the library, so I built it myself.
Keeping expectations honest: this is a simple part, not a realistic or true-to-size one. All I needed was every pin broken out and labeled so I could draw wiring diagrams against a microcontroller, not a manufacturable footprint.
Pinout matches the cable: VCC, SCK, BUSY, DC, RST, MISO, MOSI, FCSM, ECSM, GND. Breadboard, schematic, and PCB views are all included, plus a variant with a small e-paper panel graphic already attached for cleaner wiring diagrams. There’s also a J3 jumper marked on the board graphic, since getting that setting wrong (10µH vs 47µH inductor path) is a common gotcha with this board.

Feedback welcome, second custom part I’ve made.
