Questions
How big is the Pco2-sensor board PCB?
It measures 101.6 × 76.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Pco2-sensor board use?
154 parts, built around the MSP430FR5994IPNR, MAX3224EETP+, SN74LVC1G240DBVR-TP and BME280. 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 Pco2-sensor board KiCad files?
From the NOAA-PMEL/ASVCO2 repository on GitHub, at the commit this page was made from: the board is pCO2Sensor/Electrical/pco2-sensor-board.kicad_pcb and its schematic FlowController/Electrical/DRV8823-A.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pco2-sensor board design in my own project?
Its repository states no licence, so its author keeps all rights: ask NOAA-PMEL before reusing the design.
