Questions
How big is the Eink digit clk PCB?
It measures 53 × 93 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Eink digit clk use?
58 parts, built around the ESP32-C6-WROOM-1-N8, TP4057, MBR0530 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 Eink digit clk KiCad files?
From the Spritetm/eink_digit_clock repository on GitHub, at the commit this page was made from: the board is pcb/eink_digit_clk.kicad_pcb and its schematic pcb/eink_digit_clk.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Eink digit clk design in my own project?
Its repository states no licence, so its author keeps all rights: ask Spritetm before reusing the design.
