@felmue thank you for confirming . When I connect the goplus2 to core grey the green light keeps blinking when grey is off , but it seems okay with core2 . How does it work for you ? The light behaviour is same on both grey and core2 .

Do you recommend to use grey to stack goplus 2 ?

Has anyone been able to drive two DC motors from the go plus 2 and core2 stack ? I am facing a problem at motor A which only rotates on values greater than 0 to max 127 , but goes not change direction on negative values . Though motor B works absolutely fine . I tested many motors each showed same behaviour at mot A port and worked fine at mot B port .
Is my goplus2 damaged ?

goplus2 , motor A does not rotate in -127 direction but motor B does . I physically changed the motors and both run fine on motor port B .

Seems like some issue with motor port A in goplus2. Not sure if its software or hardware . Should not be hardware as motor is able to control speed from 0 to 127 on motor port A, just does not work in opposite direction .

Seems issue reported on github for goplus
