Questions
How big is the CH32V003 CO2 Sensor PCB?
It measures 29.2 × 40.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CH32V003 CO2 Sensor use?
30 parts, built around the AO3400A 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 CH32V003 CO2 Sensor KiCad files?
From the bitbank2/Pocket_CO2 repository on GitHub, at the commit this page was made from: the board is PCB/CH32V003_CO2_Sensor.kicad_pcb and its schematic PCB/CH32V003_CO2_Sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CH32V003 CO2 Sensor 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).
