Why Choose This?
- Only 4 wires needed: I2C interface replaces the standard 12-16 pin parallel connection, saving precious GPIO pins for sensors, motors, and other peripherals.
- Pre-soldered I2C backpack: PCF8574 adapter comes factory-attached - no extra soldering or assembly required out of the box.
- Crisp blue-white contrast: Bright blue backlight with white character display ensures excellent readability in indoor and moderately lit environments.
- Onboard contrast potentiometer: Fine-tune character visibility with a single screwdriver turn - no external resistor networks needed.
- HD44780 compatible: Works with the industry-standard controller, supported by virtually every microcontroller platform and programming language.
- Plug-and-play with Arduino: Install the LiquidCrystal_I2C library, connect 4 wires, upload the example sketch, and see text on screen in under 5 minutes.
- Daisy-chainable I2C bus: Connect multiple I2C devices (sensors, EEPROM, RTC) on the same two-wire bus alongside this LCD.
- Configurable I2C address: Solder pads on the backpack let you change the address, allowing up to 8 LCDs on a single I2C bus.
- 100% authentic from trusted suppliers: Genuine HD44780-based display with reliable PCF8574 I/O expander.
- 1-5 day shipping, 7-8 day delivery from Bengaluru warehouse: Fast delivery across India with same-day dispatch in Bengaluru.
- Expert technical support included: Get help with wiring, code, and troubleshooting from our engineering team.
Project Ideas
- Real-Time Clock Display: Pair with a DS3231 RTC module to build a desktop clock showing time, date, and temperature - all on the I2C bus with just 4 shared wires.
- Weather Station Dashboard: Connect a DHT22 or BME280 sensor to display live temperature, humidity, and barometric pressure readings on the LCD.
- IoT System Status Monitor: Use with ESP8266 or ESP32 to show Wi-Fi connection status, IP address, MQTT messages, or API data from the cloud.
- Smart Home Control Panel: Display menu options for controlling lights, fans, and appliances using push buttons or a rotary encoder alongside the LCD.
- Arduino Voltmeter / Multimeter: Read analog voltage, current (via INA219), or resistance values and display
