<![CDATA[CoreS3 and Goplus2]]>Hello!
I have a CoreS3 and want to know if it is compatible with the Goplus2 Module for controlling servos and dc motors.
Must i remove the battery?
Greetings,
Paul

I don't see solder jumpers and I cannot find the source code for the firmware running in M5GoPlus2 so no, I don't think you can easily modify the I2C address.

Thanks
Felix

Thanks for your response!
That's a pity though. I already have the modules here but did not try to connect. Does the goplus2 have any solder jumpers for modifying the address or is it hard coded?
Or maybe it will run with my old m5stack gray...

Greetings,
Paul

well, there is an I2C address conflict between M5CoreS3 Touch and M5GoPlus2 as both use I2C address 0x38.

Interestingly when I use M5CoreS3 with M5GoPlus2 in UIFlow2 I can control a servo and use the touch screen. However this is only true for servo 1,2 and 4. When I try to use servo 3 the system locks up.

Note: I have not tried to control DC motors.

So I'd expect some issues and do not recommend to use M5GoPlus2 with M5CoreS3.

Thanks
Felix
