Gy91 I2C address

[Sascha1234]

I tried to install a new GY91 and saw some I.O. errors in my logfile. I checked the I2C address on this board and it doesn't fit to the sensors.go [MPUREG_WHO_AM_I= 0x75]. The Address is 0x76 can someone give me some help to change it?

thanks a lot
Sascha

for the MPU9250, the address should be 0x75 (and the value should be 0x71).. What makes you think it should be 0x76? What chip do you have on there...? Did they change it again?

@b3nn0 I had the same issue with the AHRS bought 2 months ago. Same i2cdetect output as shown above.

A build of current master solved the issue for me 👍

@VirusPilot
Check your link, I don't know why but we have a 404 error. This is works: https://github.com/VirusPilot/stratux-pi4

Is it works with a raspberry 3B+ ?

[VirusPilot]

Yes, it works with a 3B+

Link above should be corrected now.

Many thanks. Built the beta image and resolved my issue with this GY-91 : https://www.amazon.co.uk/gp/product/B07DJ5L1YW

** edit— I installed the beta and it seems to be working fine with the US install.

@b3nn0, sorry to jump in this EU thread… I’m building my first Stratux in the US and hav ethe same GY-91 chip with “75” and I was wondering how I can correct this issue so it recognizes it. Cheers.
