Questions
How big is the Vaer PCB?
It measures 90 × 65 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vaer use?
44 parts, built around the ESP32-S3-WROOM-1-N8, BME280, BQ24073RGTR and USB6B1. 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 Vaer KiCad files?
From the flying7eleven/vaer repository on GitHub, at the commit this page was made from: the board is board/Vaer.kicad_pcb and its schematic board/Vaer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vaer design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
