This is so awesome! I really love the nonsoldering setup (it's not hard to solder, just annoying in a small apartment with kids). I'm going to see if they're equivalent parts with Qwiic / STEMMA connectors instead of header breakout.
Edit: Did not notice you were OP! Do you have more clarity on the calibration? Is there a buffer solution you can recommend?
Hopefully my reply to xupybd above should share light on calibration. The device doesn't have onboard memory, so you use the software to get calibration data, then save it to either your program file, or save/load to a file, memory, db etc depending on your setup.
