Questions
How big is the HD150-mod PCB?
It measures 29.2 × 38.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HD150-mod use?
30 parts, built around the E104-BT53, MCP73831, TPS70936DBV and NVR1P02. 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 HD150-mod KiCad files?
From the OpenEPaperLink/Hardware repository on GitHub, at the commit this page was made from: the board is Modchip by stevew817/HD150-mod-ebyte/HD150-mod.kicad_pcb and its schematic 2.9 Flasher by Jonas/jig2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HD150-mod design in my own project?
Its repository states no licence, so its author keeps all rights: ask OpenEPaperLink before reusing the design.
