Nokia 5110 Graphic LCD Display Module (Blue Backlight)

Bring a classic, retro aesthetic to your next electronics project with the ultra-reliable Nokia 5110 LCD Display Module. Originally famous for powering the iconic Nokia 5110 mobile phone, this graphic display has become a legendary staple in the maker community due to its exceptional readability, low power consumption, and absolute ease of use.

Featuring an $84\times 48$ pixel matrix, this screen isn’t just for text—it allows you to easily render custom graphics, bitmaps, UI menus, and complex data readouts on a striking, vibrant blue backlit background.

Key Features

• Vibrant Blue Backlight: Offers sharp contrast and fantastic nighttime legibility. The backlight can be controlled programmatically, allowing you to turn it off to save power during daylight hours.

• High Readability in Daylight: Unlike modern OLED or TFT screens that wash out under bright sunlight, this monochrome LCD utilizes reflective technology, making it perfectly readable even in direct sunlight.

• Full Graphical Freedom: With its $84\times 48$ individual monochrome pixels, you are not limited to fixed characters. You can draw lines, circles, custom fonts, icons, and even simple animations.

• Efficient SPI Interface: Uses a lightweight serial bus interface (similar to standard SPI) that only requires 5 digital I/O pins, leaving plenty of pins open on your Arduino, Raspberry Pi, or ESP32 for sensors and actuators.

• Ultra-Low Power Consumption: Runs incredibly efficiently, making it the perfect choice for battery-powered instruments, portable data loggers, and wearable tech.

Specifications

• Resolution: 84 x 48 Pixels (Monochrome)

• Controller Chip: PCD8544

• Operating Voltage: $2.7\text{V}$ to $3.3\text{V}$ DC (Note: Logic levels should be $3.3\text{V}$; use level shifters if pairing with a $5\text{V}$ Arduino)

• Backlight Supply Voltage: $3.3\text{V}$ Max

• Interface: Serial SPI (CLK, DIN, D/C, CE, RST)

• Module Dimensions: Approx. $45\text{mm}\times 45\text{mm}$

• Display Color: Black pixels on a blue illuminated background

Common Applications

• Vintage Retro Gaming: Perfect for building DIY handheld mini-consoles (like running a custom “Snake” or “Tetris” clone).

• Portable Weather Stations: Displaying live temperature, humidity trends, and weather icons on battery power.

• Diagnostic Tools: Creating compact, handheld testers, voltage meters, or diagnostic readouts for field testing.

• Robotics Interfaces: Giving your robot a face with changing expressions, or providing a clean local setup menu.

Important Setup Note: The PCD8544 controller chip is strictly a $3.3\text{V}$ device. If you are connecting it to a $5\text{V}$ microcontroller (like the Arduino Uno), it is highly recommended to use inline $10\text{k}\Omega$ resistors or a logic level converter on the data lines to protect the display.
