Hello guys, I wasn't happy to hear that the mag internal didn't work and the cheap GPS from banggood wouldnt work well. I dedicated the last week to tune and test it and I got a dead solid fix for absolute position as well as the Return to base with auto landing within like 30 cm off . If anybody is interested to know the steps I did let me know! I could also make a video.
my quad: emax motors, cheap 12amps kingkong esc, Revolution board from aliexpress (removed the capacitor cause of Baro variation now its perfect), 1800Mah 65C zop power, and a few little tricks to make sure all worked! I am so happy
Everybody is only optimistic on the social networks.. being real is hard nowadays

Interesting, but not sure is reliable.
What fusion algorithm did you use ?

that shows only openpilot design board not the clone from china

see hope its correct
measured all caps around it , that is the only one that has 0 ohm on that pin

Without the scale the scope show nothing... What's the delta ?

Short term spikes are around 0.6m, no issue.

This is the raw reading from sensor, no filtering.
