Questions
How big is the Einkpicframe PCB?
It measures 155.5 × 130 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Einkpicframe use?
60 parts, built around the ESP32-C3-WROOM-02-H4, MBR0530, AO3401 and AO3400. 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 Einkpicframe KiCad files?
From the Spritetm/picframe_colepd repository on GitHub, at the commit this page was made from: the board is pcb/einkpicframe.kicad_pcb and its schematic pcb/einkpicframe.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Einkpicframe design in my own project?
Its repository states no licence, so its author keeps all rights: ask Spritetm before reusing the design.
