Hi all - so, total newbie here 
I see that a lot of you have found the BNO08Xs to be sold out or being very expensive. My question is then; what is an alternative?
I want to make something like this (not my code) and donāt know much about the hardware 
Hope someone can help,
Thank you
Update: After some more research; seems like the answer is no and patience (or a lot of money).
The teejet (1 unit) and trimble (2 units) systems use SSS gyroscopes.
If anyone wants I can add a photo of the two modules.
The trimble gyroscopes require writing your own code to filter its raw data. They also are the cause of trimbles signature starting wiggle.
The beauty of the new imuās is they are an integrated gyro+accelerometer+magnetomer.
Plus they crunch the data themselves and spit out just the direction data.
If the current world situation would resolve we would be swimming in the new IMUs.
For those people, who wants to know whats inside Trimble autosense

Its amazing they still use the same looking sensor from the 2002, ez steer 150. 20 years goes by so fast.
Everyone knows that it is difficult to acquire IMU units.
Is this model good and can it be used?
Should work. I believe only 3.3v, GND, SDA, and SCL are required to connect the I2C bus to the Teensy.
Yes. Itās a Sparkfun model (PCB itās OPen Source)
Ardusimple has BNO085, contact tanya@ardusimple.com. They sell for 150ā¬/unit.
For those who intrested!
Crazy, they were Ā£17 last year.
ordered last week here and arrived today
