After testing 7 #LilyGO #TBeamSupreme units, one thing is clear:

👉 Magnetometer calibration is not transferable between devices.

Even in similar environments, raw readings varied dramatically between units. Proper calibration isn’t optional—it’s per-device.

I also looked at how #Meshtastic handles the onboard #QMC6310… and it essentially doesn’t (no heading, no calibration).

I'm building a lightweight, low power, waterproof, #multisensor, configurable #magnetometer for #geophysics and #geophysical site investigation. Logging with low power Linux SBC (Pi/Pocketbeagle). Interested in helping fund the project for discount prototypes? DM me. 10,000-250,000 nanoTesla sensitivity range less than 1kilo per meter of array. Maybe less. Easily flown with a drone, your choice of GPS.

"Juice’s first taste of science from space"

"ESA’s Jupiter Icy Moons Explorer, Juice, has recorded magnetic field data as its 10.6 m-long magnetometer boom deployed. .. The Juice magnetometer boom (J-MAG) was deployed on 21 April, when Juice was about 1.7 million km from Earth."
