4.3  Color Graphic LCD Installation 

 
Here is the installation instruction to install the Nokia 6610 color graphic LCD. You will need a 

different firmware package for the color LCD. 

4.3.1  What you need 

 

•

 

Yampp3U revision C or newer. 

•

 

Nokia 6610 Color LCD using the Phillips or Epson controller. 

•

 

Firmware version 3.00 or higher. 

•

 

330 ohm / 0.5w resistor for the display backlight or a white led driver module. 

•

 

One 1N4148 diode, only if you have Epson based display module. 

4.3.2 Display 

Connections 

 

If you have the Phillips based controller, you should see 11 gold pads after removing the sticker 

on the backside of the display. You can solder wires directly on these gold pads. Solder carefully 
without using too much heat. Pin 9 and pin 10 from LCD are used for backlight connections. 

 

If you have the Epson based controller, you will not find the gold pads. You must use a connector 

or you can solder the wires directly on it. Additionally you must insert a 1N4148 diode in series 

with the display power lines. Connect anode to pin1 of J9 and connect cathode to pins 1+6 of the 

display. 

4.3.2.1 Display Signal 

 

The next picture will guide you to connect display wires on the Yampp connector (J9).
