Questions
How big is the Pico sensor pcb PCB?
It measures 56 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pico sensor pcb use?
39 parts, built around the AHT20, BH1750FVI-TR and MP34DT05TR-A. 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 Pico sensor pcb KiCad files?
From the bablokb/pcb-datalogger-sensor-pcb repository on GitHub, at the commit this page was made from: the board is pico-sensor-pcb.kicad_pcb and its schematic pico-sensor-pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pico sensor pcb design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
