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

Crocodile Alligator Clip 50 mm Black and Red
Description: An alligator clip, also called a spring clip, creates a temporary electrical connection using a simple mechanical design.It gets its name because the jaws resemble an alligator or crocodile’s mouth, opening and closing to grip objects securely.The clip works like a spring-loaded clothespin that uses tapered, serrated jaws to hold wires or metal parts tightly.A spring pushes the jaws together, allowing the clip to grip objects and maintain a reliable electrical connection.Manufacturers design these clips for electronics testing, enabling quick connections without soldering or permanent joints.One jaw usually connects to a wire by crimping or soldering for efficient current transfer.Some clips use a bent jaw forming the inner contact of a 15 mm to 4 mm female banana jack.This design allows a fast, non-permanent connection between test circuits and laboratory instruments.A plastic cover or boot surrounds the clip to prevent short circuits and protect users from accidental shocks.Engineers and students use these clips widely in testing, prototyping, and educational experiments. Applications: Technicians use small clips (15 mm–40 mm) in electrical laboratories, schools, and college labs for quick test connections.Large clips, called automotive clips or battery clamps, use solid copper for low resistance and strong current flow.Users connect these large clips with thick insulated copper cables between automobile batteries or heavy electrical systems.Hobbyists and professionals rely on these clips for safe, reusable, and efficient electrical connections. Product Example: Check the Crocodile Alligator Clip 50 mm – Red and Black, made from durable stainless steel with a protective plastic shroud.Its spring-loaded jaws open wide to grip different wire sizes securely during testing or circuit connection.The serrated teeth ensure a strong, slip-free grip that maintains stable electrical contact during operation.
