Nokia 5110 LCD Module | 84×48 Graphic Display | PCD8544
Product Overview
The Nokia 5110 LCD from Pro Tronix is a repurposed classic from the mobile phone era, now optimized for the maker community. Unlike character LCDs (like the 1602) which only display fixed letters, this is a Graphic LCD, meaning you have control over every single one of its 4,032 pixels.
Built around the PCD8544 controller, it uses a low-power CMOS design. It is highly prized for handheld devices because the screen is reflective; the brighter the sun, the easier it is to read. It features a gentle backlight for dark environments and communicates via a fast SPI interface, providing a smooth refresh rate for simple animations or real-time graphing.

Key Features
Full Graphic Control: Draw lines, circles, custom icons, and varied text fonts with ease.
Sunlight Readable: Excellent visibility in outdoor conditions without needing a high-power backlight.
Ultra-Low Consumption: One of the most energy-efficient displays available, ideal for long-term battery projects.
Compact Footprint: Perfect for small enclosures where a 16×2 LCD would be too bulky.
Common Applications
Retro Handheld Games: Building “Snake” or “Pong” clones on an Arduino.
Portable Instrumentation: Displaying signal waves (Mini Oscilloscopes) or battery discharge graphs.
Low-Power Weather Nodes: Creating a battery-operated station that lasts months on a single charge.
Digital Compasses: Displaying a graphical needle and heading data for outdoor navigation.
⚠️ Important Usage Note: The Nokia 5110 is primarily a 3.3V device. When using it with a 5V Arduino Uno/Mega, it is highly recommended to use current-limiting resistors or a logic level shifter on the data lines to protect the PCD8544 controller.
