LCD1602 I2C
The LCD1602 I2C display is an upgraded version of the standard 16×2 LCD, equipped with an I2C (Inter-Integrated Circuit) adapter. This reduces the required microcontroller pins from 16+ to just 2 (SDA and SCL), making it highly efficient for projects with limited GPIO availability. It still features 16 characters × 2 lines, each formed on a 5×8 dot matrix, and supports adjustable backlight and contrast.

Key Features:
- 16×2 character display with I2C interface
- Requires only 2 pins (SDA, SCL) for communication
- Works with 5V (some modules support 3.3V)
- Adjustable backlight and contrast via onboard potentiometer
- Compatible with Arduino, STM32, ESP32, Raspberry Pi
Applications:
- IoT and embedded systems with limited GPIOs
- Compact DIY electronics and hobby projects
- Home appliances and monitoring systems
- Industrial devices needing simple text output
