Questions
How big is the Mainboard PCB?
It measures 106 × 80 mm and has 4 copper layers, 1.58 mm thick.
What parts does the Mainboard use?
152 parts, built around the ESP32-S3-WROOM-1-N8, PCAL6416AHF, TPS62823DLC and PCA9306JKZ. 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 Mainboard KiCad files?
From the PyroVision-ThermalCam/Mainboard repository on GitHub, at the commit this page was made from: the board is mainboard/Mainboard.kicad_pcb and its schematic mainboard/Battery.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mainboard design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
