Questions
How big is the Telemetry Primary PCB?
It measures 95 × 82 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Telemetry Primary use?
148 parts, built around the CP2102N-A01-GQFN24, LAN8742A-CZ-TR, RI3-1205S and BNO055. 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 Telemetry Primary KiCad files?
From the lhr-solar/DataAcq-SunlightPCB repository on GitHub, at the commit this page was made from: the board is Telemetry-Primary.kicad_pcb and its schematic CAN.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Telemetry Primary design in my own project?
Its repository states no licence, so its author keeps all rights: ask lhr-solar before reusing the design.
