TFT Specifications

The MTF-T035 320x240 3.5" color TFT display from Microtips was once the default TFT display supported on APF9328. Two pin compatible versions of this LCD are available: one with touchscreen (analog outputs) and one without. The MTF-T035 is provided with a 4 white led backlight.

The specification can be found here: [1]


Some photos are although available here: Board Pictures

Warning Warning: the TFT equipped with a touch panel requires an external touch controller which is not on the LCD_Adapt. This is due to the fact that the touch panel option was not available when the LCD_adapt was designed.

Nevertheless, the touch controller will be present on the DevFull board.

Adapter Board

figure 1 - MTF-T035 picture

This kind of LCD requires an adapter board. The small board generates the required bias voltages, integrates a white led driver and provides a standard 2.54 connector interface. It has to be noted that only a 3.3V supply is required.

The specification can be found here: [2]

The schematics can be found here: [3]

The assembly drawings can be found here: [4]

Note that the pin 1 of the connectors are although written in the top layer copper.

Connecting the LCD to the adapter board

Open connector, plug & align LCD Flex pin 1 and PCB pin 1
Close connector

Connection with the APF9328DevLight v1.0

Just connect signals with same names together. Use the shortest wires you can !

The DevLight schematics and specification may be usefull: [5]

Once done, verify the connections with a multimeter.

Warning Warning: Do not forget to check the 3.3V supply polarity on the LCD_adapt board before to power up the system !

Connection with the APF9328DevLight v2 & the APF9328DevFull

Use a straight flat cable and connect pin 1 to pin 1. (Same way as LQ043).


  • If your LCD shows too much White then set the potentiometer on the LCD_Adapt to the minimum value.
