Nokia 3310 / 5110 display board
had to extract it from the game boy programmer / cartridge project
Almost makes no sense to design a board for this cheap display, when you get it with a pcb by paying 50ct or so more. I'm going to add RGB LEDs to give those displays another "dimension" to work with and make them 5V tolerant.
This is pin compatible to the adafruit board, where the LED pin is the RED pin. Sparkfun makes them different. Cheap eBay clones have a different pinout as well.
84x48 Pixel of the monochromest kind.

I'm seriously considering to fix the minor problems, make another batch and sell them. Here are some thoughts and questions.
- it's simple to understand
- easy to integrate into projects
- it's different enough from the original LCD modules
- parts are affordable, which keeps BOM small
Design considerations
- should I add a controller for the RGB led?
- should I connect via SPI or I2C?
- I2C: more pins on the header, Attiny possible
- SPI: too many pins for attiny, LED pin reusable as CS
- or even use WS2812b protocol
- LED pin reusable as DIN
- requires timey-wimey stuff
- get attiny or original controller chip
- leave it as is, use 2 extra pins, let the customer worry
- design pinout like sparkfun, adafruit or cheap eBay boards?
- idea here is to make it easy to swap
- keep it 5V?
Pricing
could be around 10 Euros and still have a good margin.
