0.96 128x64 Oled Lcd Blue With Buttons

0.96 Inch Blue Oled Module With 4 Buttons

3.3V 5V SSD1306 128x64 Pixel IIC I2C Serial 0.96”  Screen Lcd Indicator Arduino STM32 ESP32

     It is a ready interface module offering an SSD1306 driven 0.96 inch blue oled display and 4 buttons together. With 128x64 pixel resolution and high contrast ratio, it provides a readable image despite its small size. It works with bright blue pixels on a black background, requires no backlight and consumes low power.

     It connects to the microcontroller over only two signal lines (SCL, SDA) with the I2C communication protocol. Since the SSD1306 driver IC is embedded inside the display, no external component is required. It can be used directly with Arduino, ESP32, STM32, MSP430 and 8051 series microcontrollers. It can be run with the Adafruit SSD1306 library. The I2C address of the products in stock may vary, it is recommended to perform an address scan before use.

     The 4 buttons on the board have 4.7K pull-up resistors and pull to ground when pressed. With this structure, menu navigation and user input operations can be implemented without requiring additional circuitry. Connection is provided over an 8 pin male header. It works with 3.3V or 5V supply.
