I2C RGB Backlight LCD 16x2 Display Module for Arduino (Black Text) - DFRobot SKU: DFR0374

I've just done a I2C scan of the device connected to a DFRobot UNO and I go the following results:

I2C device found at address 0x2D  !

I2C device found at address 0x3E  !

I know  0x2D is the LCD1602 RGB Module, but what device is on 0x3E ?

I would be greatful for any help

Thanks,

Rob
