Questions
How big is the ZumoComSystem PCB?
It measures 66 × 86.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ZumoComSystem use?
98 parts, built around the ESP32-S3-WROOM-1-N8, S-8252AAL-M6T1U, RQ5E065AJTCL and SD03C-7-ES. 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 ZumoComSystem KiCad files?
From the NewTec-GmbH/ZumoComSystemHW repository on GitHub, at the commit this page was made from: the board is implementation/ZumoComSystem.kicad_pcb and its schematic implementation/Battery.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ZumoComSystem design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
