Nokia 5110 Booster Pack

Recommended Posts

I have seen 4 different pinout/connector locations for those BOBs. If you buy from eBay be aware you may not get exactly what is shown in the picture.

 

The parts on the board vary too. For example the LED backlight may go directly to the header pin, or have a single resistor for all LEDs, or a resistor for each LED, and in some cases a resistor for each LED and a transistor.

New version of my Nokia 5110 Booster Pack.

Additions include optional memory chip and MCU (MSP430G2553 for example.)

MCU will allow this board to be used as a stand-alone display board, memory can be used as a display buffer.

Schematic for the new board. Note that some of the connections have changed. There's also backlight resistor which can be shorted (couple of white LEDs blew on one of my 5110s so I decided to add it just in case.)

If you solder MCU and headers, make sure you remove MCU from the LaunchPad when plugging it in for programming.
