Does anyone have the pin outs for the Funduino I2C board - I want to connect to the display backlight LED to control brightness from a PWM pin on Arduino but can't see if the board jumper is connected by a resistor or not. Removing the two pin Molex jumper turns off the LED so it's connected in some way but I don't want to damage the board or the Controller by connecting inappropiatly. Can anyone help?
