Questions
How big is the E track PCB?
It measures 40 × 40 mm and has 2 copper layers, 1 mm thick.
What parts does the E track use?
40 parts, built around the ESP32-C3-MINI-1, BME280, TPS62842DGRR and PCF8563TS/5. 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 E track KiCad files?
From the picli3/e-tracker repository on GitHub, at the commit this page was made from: the board is e-track.kicad_pcb and its schematic Power_Manager.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the E track design in my own project?
Its repository states no licence, so its author keeps all rights: ask picli3 before reusing the design.
