      I dont know what pin number is using. How to map properly to receive data via I2C, what pin numbers I need to map to follow a OpenMV example? Are they the same that than in MAIX boards?

        The pins for the Grove ports are listed in this work in progress document

              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
