Questions
How big is the EnvDaqBox PCB?
It measures 96.3 × 71 mm and has 4 copper layers, 1.6 mm thick.
What parts does the EnvDaqBox use?
96 parts, built around the ESP32-C6-MINI-1U-H4, TPS56A37RPAR, TSU111HYLT and CH224Q. 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 EnvDaqBox KiCad files?
From the Yongci/EnvDaqBox-PCB repository on GitHub, at the commit this page was made from: the board is EnvDaqBox.kicad_pcb and its schematic EnvDaqBox.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EnvDaqBox design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
