Nokia 3310 Upgraded with A Custom PCB - Adafruit Blog

Hoani Bryson has upgraded a classic Nokia 3310 by creating a custom printed circuit board (PCB) to support his game, "Trick Shot II," which won first place in the Nokia 3310 Jam. The challenge was to develop a game that adhered to the constraints of the original Nokia 3310, including a monochrome display with a resolution of 84x48 pixels and audio limited to a single buzzer.
