The SSD1306 0.96-inch OLED Display Module is a high-contrast, energy-efficient solution for adding a premium visual interface to your electronics. At Electrapac, we recommend this OLED over standard LCDs because it doesn't require a backlight—each pixel is its own light source, resulting in deep blacks and vivid clarity.

Product Overview

This compact display features a resolution of 128x64 pixels, allowing you to render sharp text, detailed icons, and even basic graphics. Because it uses OLED technology, it consumes significantly less power than traditional displays, making it the go-to choice for battery-powered wearables and IoT devices.

Key Features for Electrapac Customers

• Self-Illuminating Pixels: Since there is no backlight, the display is incredibly thin and offers a much higher contrast ratio than 1602 LCDs.

• Minimalist Wiring: The I2C interface requires only 4 wires (VCC, GND, SDA, SCL), saving your microcontroller's pins for other sensors.

• Extreme Viewing Angles: The screen remains perfectly readable from almost any side (up to 160 degrees), unlike standard screens that wash out when tilted.

• Versatile Library Support: Fully compatible with popular libraries like Adafruit_SSD1306 and U8g2, making it easy to display everything from "Hello World" to real-time graphs.

• Wide Voltage Range: An onboard voltage regulator allows it to work seamlessly with both 3.3V (ESP32/Raspberry Pi) and 5V (Arduino Uno/Mega) logic.

Wiring & Setup Guide

For the best performance from www.electrapac.com, follow this I2C connection map:

1. VCC: Connect to 3.3V or 5V.

2. GND: Connect to Ground.

3. SCL (Clock): Connect to Arduino A5 (or the dedicated SCL pin).

4. SDA (Data): Connect to Arduino A4 (or the dedicated SDA pin).

Pro-Tip: Most SSD1306 modules use the I2C address 0x3C. If your code isn't working, double-check if your module is set to 0x3D by looking at the solder jumper on the back of the PCB.

Primary Applications

• Smart Watches & Wearables: Its tiny size and low power draw are perfect for portable gear.

• Sensor Dashboards: Display real-time temperature, humidity, or heart rate data.

• IoT Nodes: Show Wi-Fi signal strength, IP addresses, or cloud connection status.

• Diagnostic Tools: Build your own mini-multimeter or battery capacity tester.

Why Shop at Electrapac?

We source SSD1306 OLEDs with high-purity organic layers to ensure long-lasting brightness and no "screen burn" during normal use. Visit www.electrapac.com to find this display, jumper wires, and compatible I2C sensors.
