Out of stock0.96 Inch Blue SPI OLED Display Module 7-Pin 128×64 – SSD1306
[LED/LCD Display] 0.96 Inch Blue SPI OLED Display Module 7-Pin 128×64 – SSD1306 The 0.96-inch Blue OLED Display Module is a compact graphical display based on the SSD1306 driver IC, featuring a 128×64 pixel resolution and blue monochrome display. This version has a 7-pin interface with a dedicated CS (Chip Select) pin, making it suitable for 4-wire SPI communication. The module is factory-configured for SPI and can also be modified for I2C/IIC communication on compatible board versions. With its compact size, wide viewing angle and low-power OLED technology, it is suitable for Arduino, ESP32, ESP8266, STM32, Raspberry Pi and other microcontroller projects. ⭐ Key Features 0.96-inch blue OLED display 128 × 64 pixel resolution SSD1306 driver IC 7-pin interface Dedicated CS (Chip Select) pin Factory configured for 4-wire SPI Supports SPI and I2C/IIC with appropriate configuration 3.3V/5V compatible on supported module versions No backlight required Low power consumption Wide viewing angle of more than 160° Compact PCB design Pre-soldered 7-pin male header Compatible with Arduino, ESP32, ESP8266, STM32 and Raspberry Pi projects 📋 Technical Specifications Display Type: OLED (Organic Light-Emitting Diode) Display Colour: Blue Display Size: 0.96 inch Driver IC: SSD1306 Resolution: 128 × 64 pixels Interface: SPI / I2C Default Interface: 4-wire SPI Input Voltage: 3.3V–5V Viewing Angle: >160° Module Dimensions: Approximately 27 × 27 × 4mm Operating Temperature: Approximately -30°C to +70°C Header: 7-pin male header, pre-soldered Display Type: Monochrome blue OLED 🔌 7-Pin Interface The 7-pin version provides the following connections: GND – Ground VCC – Power supply D0 / SCK / CLK – SPI clock D1 / MOSI / SDA – SPI data RES / RST – Display reset DC / A0 – Data/Command selection CS – Chip Select 🛠️ SPI Connection The module is normally supplied in 4-wire SPI configuration. For an Arduino Uno, a typical connection is: VCC → 5V GND → GND D0 → SCK / D13 D1 → MOSI / D11 RES → Digital I/O DC → Digital I/O CS → Digital I/O The dedicated CS pin allows the OLED to share the SPI bus with other devices such as SD cards or additional SPI peripherals. 🔄 I2C / IIC Configuration On compatible versions, the module can be converted from SPI to I2C by changing the appropriate resistor configuration on the PCB. The supplied board configuration may require: Moving the resistor from R3 to R1 Shorting R8 with solder Using D0 as SCL Using D1 as SDA Configuring DC for the I2C address The exact resistor positions can vary between board revisions, so check the markings on your particular PCB before modification. 🎯 Applications Arduino projects ESP32 projects ESP8266 projects STM32 development Raspberry Pi projects IoT devices Sensor displays Voltage/current meters Battery monitors Temperature displays Digital clocks Data loggers Portable electronic devices Robotics DIY measuring instruments Embedded systems Menu and status displays 💡 Advantages of OLED OLED technology is self-emissive, meaning the pixels produce their own light and do not require a conventional backlight. This provides high contrast, compact construction and a wide viewing angle while keeping power consumption relatively low. ⚠️ Important Notes This is the 7-pin SPI version, not the 6-pin version. The module is normally configured for SPI communication. Check the PCB labels before connecting the module. Do not exceed the specified supply voltage. Although many versions support 5V operation, the exact voltage tolerance can vary between board revisions. I2C operation may require hardware resistor modification. The actual PCB layout and component markings may vary slightly between production batches. Display colour: Blue. Libraries such as Adafruit SSD1306 and U8g2 can be used with compatible microcontrollers. 📦 Package Includes 1 × 0.96 Inch Blue SPI OLED Display Module
