Questions
How big is the Anchor7 PCB?
It measures 72.3 × 72.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Anchor7 use?
84 parts, built around the ESP32-WROOM-32, MP24971DS, PAM8304ASR and ZLDO1117G33TA. 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 Anchor7 KiCad files?
From the jmpinit/babel-hardware repository on GitHub, at the commit this page was made from: the board is Anchor7/Anchor7.kicad_pcb and its schematic Anchor7/Anchor7.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Anchor7 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jmpinit before reusing the design.
