µLCD-24PTU, µLCD-28PTU, µLCD-32PTU and µLCD-32WPTU microLCD Modules

3.3.

The µLCD-24/28/32/32WPTU modules connect to the 4DevBoard on the 10-pin and 30-pin vertical female

headers, as depicted in the image below.

When the display module is attached to the 4DevBoard, the pins of the module are replicated on the lower 10-

pin and 30-pin male headers.

The pin configuration of this 10-pin male header is as follows:

Note: rather than the display module generating voltage for the 3.3V OUT pin, the 3.3V available on this

header comes from the on-board voltage regulator of the 4DevBoard, which can provide a higher current.

To program the display module, connect your 4D Programming Cable to the right hand side of this 10-pin male

header, ensuring you have the cable the correct way around.

Note: Failure to connect the module in the correct orientation or if an offset on the pins is made when

plugging the module it, may result in a short circuit and damage your display module. Please ensure that the

4DevBoard is disconnected from power when connecting your display module.

For further information on how to program your display module, please refer to the individual datasheet for

the display module in question, available from the 4D Systems website,
