I designed a simple Nokia LCD Breakout board which allows you to interface any Nokia 6100 compatible display to microcontroller like PIC and AVR. The board itself provides 6.8volts for the backlight by a simple boost converter built up using a common 555 timer IC. There’s a switch to choose whether you want to work with 5V logic, or with 3.3V logic.
Reasons I started this project:
Features of this board:
- 5V and 3.3V logic selectable by a switch.
- Uses easy DIP components and also for the SMD components a room is provided such that parts from 0603 to 1206 and even 1809 can be soldered in same pad for some components. This eliminates the need of good experiences in soldering SMD components.
- The LCD is placed over small and SMD parts by a bi-sided foam tape. Large DIP and SMD parts as inductor, 555IC, switch etc are placed in other side.
- Can be placed on breadboard for interface by PIC, AVR etc and since the LCD uses SPI interface, you can use BusPirate to talk to it also.
- You can replace the parts with any near valued parts, about 10% tolerance will have no negative effect.
Compatible LCDs include Nokia 3100, 3120, 5100, 6100, 6610, 7210, 7250, 2600 (costs 3$), 1600, 2650, 2652, 3200, 5140, 6220, 6225.
Documentation and files are available in the forum, PCBs will be available soon.

Cool. I’ve wanted something like this for a while to take advantage of those cheap lcds. Well done!
This is nice, but how do I go about mounting it to something? Double stick tape? Yuck…
Hi Drone,
I’m already working on a new version where many improvements are made. And yes, there are mounting holes too. The version will be available in the forum in few days. Take a look here: bit.ly/rnlkoR
Anyone care to share the link to where I can get these displays for $3?
Thanks in advance!
Hi Mat,
Actually, you can search in local mobile spares shop with the list to buy the lowest cost compatible LCD. Otherwise if you opt for buying online, a big cost will arise as shipping. Anyways you can search in gsmserver.com or other spare parts suppliers.
Nice touch with the 555 boost. I’m so spoiled by the various boost regulator chips that it’s refreshing to see a more discrete design.
