Overview
Eink breakout is an open-source printed circuit board by gpgreen, from the gpgreen/eink-breakout repository on GitHub, published under the MIT licence. It is a 2-layer board of 36 × 34 mm with 25 parts on 24 nets, routed with 127 tracks and 21 vias.
It is built around the MBR0530 and IRLML0100. Its parts include 12 capacitors, 3 diodes, 2 resistors, 1 IC and 1 transistor. It belongs with the lEDs and displays and interfaces and adapters boards of this library.
Main components
2README
README.mdEink-Breakout
Kicad project for a Dalian Good Display Epaper breakout board. The display GDEW042T2 has a 24pin flat panel cable. The display is controlled with the SPI bus, so the display SPI pins are passed to a JST PH connector.
Note: R1 is shown on the datasheet example circuit. It is not needed so should not be populated on the board.
Functions
The main function of the board is to translate the signals from the flat panel cable to the JST PH connector. The JST connector has signals for the SPI bus, D/C, Busy from the eink display. Also power and ground at 3.3VDC.
The rest of the conductors on the flat panel cable are connected as shown in the datasheet example wiring. There is no bus translation, everything is set at 3.3VDC.

Questions
How big is the Eink breakout PCB?
It measures 36 × 34 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Eink breakout use?
25 parts, built around the MBR0530 and IRLML0100. 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 Eink breakout KiCad files?
From the gpgreen/eink-breakout repository on GitHub, at the commit this page was made from: the board is eink-breakout.kicad_pcb and its schematic eink-breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Eink breakout 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).
