Questions
How big is the ORBIT PCB?
It measures 32 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ORBIT use?
27 parts, built around the ESP32-C6-MINI-1U-H4 and TPS63802DLAR. 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 ORBIT KiCad files?
From the Apoll011/avi-hw-mesh-node repository on GitHub, at the commit this page was made from: the board is Hardware/ORBIT.kicad_pcb and its schematic Hardware/ORBIT.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ORBIT design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
