they appear as R17, R18 and R19.

@ajb2k3 : that is interesting - thanks for sharing.

@tttttttom : sorry for misleading you.

Also interestingly these address pins are not mentioned in the schematic.

Thanks
Felix

There is a header inside that if you solder the pins, the address will change.0_1630333824840_address.png

thank you for sharing your knowledge. And yes, my question concerns the joystick UNIT. And yes, I would like to change the i2c address inside the MEGA328P. But the unit you are mentioning is also fine. I will check that ...
Regards
Tom

if I am not mistaken there is no joystick module - did you mean the joystick unit?

The joystick unit uses an MEGA328P processor inside which most likely has the I2C address programmed in it and I cannot find the source of the firmware running inside the MEGA328. Given that I would say you cannot change the I2C address.

Your best bet would be a PaHub unit which has been developed exactly to solve that use case.

Thanks
Felix
