Questions
How big is the EnvOpenSensor PCB?
It measures 89.7 × 67.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EnvOpenSensor use?
375 parts, built around the IS31FL3730-QFLS2-TR, SI7021-A20-GM, W25Q16JVUXIQ and SCD41-D-R2. 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 EnvOpenSensor KiCad files?
From the Envious-Data/EnvOpenEnvSensor repository on GitHub, at the commit this page was made from: the board is EnvOpenSensor-RP2040/EnvOpenSensor.kicad_pcb and its schematic EnvOpenSensor-ATTINY/EnvOpenSensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EnvOpenSensor design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
