As a quasi-nostalgic relic of an almost extinct generation of cell phones we use today, the Nokia 5110 LCD screen from the cellular phone with the same name, kindly as a breakout board for a small budget. Because the display operates at 3.3V, we use it together with a 8MHz clocked Arduino Pro Mini, which also runs at 3.3V.
For experimenting with more external modules and the Arduino, it’s recommended to use an external power source. Also modules with 3.3V or 5V can quickly become confusing on the workplace. A solution could be this module, which can be directly plugged onto the breadboard.
