Questions
How big is the Tracking dev PCB?
It measures 50.8 × 36.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Tracking dev use?
71 parts, built around the ATMEGA328PB-AU, SIM7000E, TPS22918DBV and CAT24C256LI. 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 Tracking dev KiCad files?
From the wrig0421/spud-hardware repository on GitHub, at the commit this page was made from: the board is Design/tracking_device/pcb/tracking_dev.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tracking dev design in my own project?
Its repository states no licence, so its author keeps all rights: ask wrig0421 before reusing the design.
