Questions
How big is the Bioreactor board PCB?
It measures 165 × 110 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bioreactor board use?
43 parts, built around the ESP32-DEVKITC-VE, MAX31865AAP+, IRLZ44N and ADS1115. 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 Bioreactor board KiCad files?
From the Agiuffra/Bioreactor_board repository on GitHub, at the commit this page was made from: the board is Bioreactor_board.kicad_pcb and its schematic Bioreactor_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bioreactor board 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).
