1602 I2C LCD Display Module - Blue Backlight, White Characters

The 1602 I2C LCD Display Module is a compact and easy-to-use alphanumeric screen that displays 2 lines of 16 characters each. This version features a blue backlight with white text, providing excellent visibility for a wide range of embedded applications. With an integrated I2C (IIC) interface, it greatly reduces the number of GPIO pins needed-from 6+ down to just 2 communication lines (SDA and SCL)-making it ideal for microcontrollers like Arduino, ESP32, or Raspberry Pi.

It runs on a typical 5V power supply (supports 2.5V to 6V) and uses a default I2C address of 0x27, which can be modified using solderable jumpers (A0, A1, A2). A built-in potentiometer on the I2C backpack allows for easy contrast adjustment. Compact and lightweight, the module fits perfectly into small enclosures or compact embedded systems. It's excellent for applications such as sensor data displays, system status monitors, clocks, and menu navigation systems.
