Questions
How big is the Binuhr tiny PCB?
It measures 44.2 × 26 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Binuhr tiny use?
52 parts, built around the ESP-WROOM-02, RT8097AHGB and NPIC6C596D. 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 Binuhr tiny KiCad files?
From the antonloof/binuhr_tiny repository on GitHub, at the commit this page was made from: the board is board/board.kicad_pcb and its schematic board/board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Binuhr tiny design in my own project?
Its repository states no licence, so its author keeps all rights: ask antonloof before reusing the design.
