dunno, i just started testing it, my first test was to find the Voltage output and couldnt find it then tried all the methods above, among others flashing the latest firmware, unless the grove port is disable via software the port could have been dead from factory

yelp mine grove port is dead, tested multiple times with a i2c IPS display and a i2c scanner on Maixpy only get 2 devices and not a 3rd [0x34 & 0x68] also not getting any voltage output and also tested with a different power source on the IPS display but still not getting detected, this just sucks cause i had plans :(

Ouch how did you kill it?
