Grove - OLED Display 1.12" unpowers Azure Sphere MT3620 Development Kit

Hi all, I’m running the following hardware configuration:
[list]

  • Azure Sphere MT3620 Development Kit
    • [/list]
    [list]
  • MT3620 Grove Shield v1.0
    • [/list]
    [list]
  • Grove - OLED Display 1.12" (128x128, SH1107G)
    • [/list]
    All Azure Sphere OS programs run fine on the board, thank you Seeed, you did a great job!



    But as soon as I connect the display to the I2C bus, it seems that the board loses power, all LEDs go dark, the connection to the development computer breaks down.



    No matter which of the two IC2 connectors of the shield I use, the phenomenon is always the same. The error does not occur when I connect a Grove Temperature & Humidity Sensor (SHT31) to the shield.



    Is the display defective? Does anyone have any ideas? Thanks in advance!

    Hi,



    Sounds looks like the OLED is short, could you please check the continuity using a multimeter to find is there any problems.
