This LCD module displays 2 lines x 16 characters and operates at 5V. It includes a potentiometer to adjust backlight and contrast for clear visibility. Key benefits Clear, compact display: shows characters, letters and numbers in a 2x16 format, suitable for essential status information. Simple wiring: four I/O pins required – VCC, GND, SDA (serial data line), SCL (serial clock line) – minimizes cabling. Easy I2C integration: supports the I2C protocol and can be controlled directly with the I2C LCD1602 library to adjust backlight and contrast. Versatile and compatible: suitable for displaying a realtime clock, temperature, and other sensor data; compatible with Pi and other microcontroller platforms. What to know about the module Display type and size: 2 lines x 16 characters. Power and control: 5V operation with onboard potentiometer for backlight and contrast adjustment. Interfaces: 4pin connection (VCC, GND, SDA, SCL). Wiring: connect GND to GND, VCC to VCC, SDA to SDA, SCL to SCL on your controller. Protocol and library: I2C protocol support; accessible via the I2C LCD1602 library to read data and adjust display parameters. Applications Realtime clock display in a home or lab setup. Environment monitoring: show temperature and humidity readings from sensors. Raspberry Pi projects: system status, time display, and quick sensor readouts on a compact display. Specific use scenarios Raspberry Pi project: display current date and time along with a room temperature reading from a temperature sensor, providing a quick status panel without a full monitor. Microcontrollerbased weather station: show current temperature and humidity on the 2x16 LCD, with a separate sensor module feeding data over I2C. Small home automation panel: display device status, network time, and alert messages in a compact, easytoread format.
