IIE/I2C 1602 Serial Character LCD 2x16 Display
130.00 EGP
The 1602 LCD display module, equipped with an I2C/IIC interface, is an electronic display used to show text and numbers across two lines. It features a serial adapter board (I2C backpack) mounted on the back, which simplifies connections and reduces the number of wires required to operate it with microcontrollers. **Technical Specifications** **Display Capacity:** 16 characters per line × 2 lines (32 characters total). **Communication Protocol:** I2C / IIC (uses only two data pins: SDA and SCL). **Operating Voltage:** 5V DC. **Default I2C Address:** Typically 0x27 or 0x3F (depending on the chip used, such as the PCF8574). **Display Color & Backlight:** Blue backlight with white text (or green backlight with black text). **Dimensions:** Approximately 80mm × 36mm × 19mm. **Key Features** **Pin Saving:** Reduces the wiring requirement from the 6–12 wires used in standard connections to just two data wires (SDA, SCL) and two power wires (VCC, GND), freeing up microcontroller pins for other components. **Contrast Adjustment:** Includes a blue potentiometer on the back to easily adjust text clarity. **Backlight Jumper:** Equipped with a removable jumper to toggle the backlight on or off, helping to conserve power. **Common Applications** Displaying readings from various sensors (e.g., temperature, humidity, distance). Displaying system status and operational notifications for Arduino, ESP32, and Raspberry Pi projects. Creating simple user interfaces and digital menus for machines and embedded devices. Important Operational Notes Initial Contrast Adjustment: If you connect the display and see only white boxes or no text, use a small screwdriver to turn the blue potentiometer located on the back of the display until the characters appear clearly. Software Libraries: It is recommended to use the LiquidCrystal_I2C library with the Arduino IDE for easier text writing and formatting.
