Questions
How big is the Kigeyes power io board PCB?
It measures 100 × 60 mm and has 4 copper layers, 1.02 mm thick.
What parts does the Kigeyes power io board use?
280 parts, built around the TPD4E02B04DQAR, USBLC6-2P6, LM73100RPW and TPS2553DBV. 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 Kigeyes power io board KiCad files?
From the jrymk/KigEyes repository on GitHub, at the commit this page was made from: the board is PCB/kigeyes-power-io-board/kigeyes-power-io-board.kicad_pcb and its schematic PCB/OVM6211-bga2lga/OVM6211-bga2lga.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kigeyes power io board design in my own project?
Its repository states no licence, so its author keeps all rights: ask jrymk before reusing the design.
