+ICTFS is the good one, but it needs some tweaks (degrees going up)
+ICTFS v0.2 idk if it worked
+ICTFS v0.3 is the one from adafruit. It works-ish, but some of the measurements are kinda faulty.
+ICTFS v0.4 needs a lot of tweaks.

+Namely,
+- roll pitch and yaw are approximately half of what they need to be
+- degrees are going up like crazy
+- degrees can go past 359 and below 0 degrees (shouldn't happen)
