Alternative I2C device for jetbot

Hello all.

Im trying to use PCF8574 module for my jetbot.
Is it possible to modify the adafruit module file and change the hex address the script is looking for? I would need to remap the outputs of course.
I can see my module at hex address 27 on the nano.

I’m also not really sure why the motor driver isn’t just run from the gpio if anyone has a good reason they can suggest?


Please refer to Jetson AGX Xavier I2C not working anymore - Jetson & Embedded Systems / Jetson AGX Xavier - NVIDIA Developer Forums to see if can help.

For others who have googled for this same question.

I’ve changed the hex address after finding the location of Adafruit motor hat file :

So far its working, some output to the wheels! need to figure out the right in1 and in2 for the driver.
