== Adapter Board ==<br />
[[Image:MTF_035_Adapt.jpg|center]]<br />
<br />
This kind of LCD requires an adapter board. <br />
The small board generates the required bias voltages, integrates a white led driver and provides a standard 2.54 connector interface. <br />
It has to be noted that only a 3.3V supply is required.<br />
<br />
The <strong>schematics</strong> can be found here:<br />

<br />
The <strong>assembly drawings</strong> can be found here:<br />

<br />
Note that the pin 1 of the connectors are although written in the top layer copper.<br />

== Connections with the DevLight ==<br />
Just connect signals with same names together. <strong>Use the shortest wires you can !</strong><br />
<br />
The DevLight schematics and specification may be usefull:<br />

<br />
Once done verify the connections by means of your multimeter. <br />
<strong>Do not forget to check the 3.3V supply polarity on the LCD_adapt board before to power up the system !</strong><br />
<br />
== Troubleshooting ==<br />
If your LCD shows too much White then set the potar on the LCD_Adapt to the minimum value.<br />
