Quick Overview
This is 2 pieces of LCD I2C 1602 modules that work with Arduino, ESP32, ESP8266, Raspberry Pi, or any 5V or 3.3V microcontroller.
Key Features
- LCD with I2C interface (4 wires)
- LCD 16x2 (16 columns 2 rows ⇒ two lines, 16 characters per line)
- Adjustable contrast via a built-in potentiometer
- Backlight can be turned on/off programmably
- Works with Arduino, ESP32, ESP8266, Raspberry Pi
- Dimension: 78mm x 34mm x 13mm (L x W x H).
- Power supply: +5V
- I2C address: 0x27
INTERFACE
- VCC pin: the power supply for the LCD, connect this pin to VCC (5V).
- GND pin: connect this pin to GND (0V).
- SCL pin: I2C clock signal pin, connect this pin to SCL of microcontroller
- SDA pin: I2C data signal pin, connect this pin to SDA of microcontroller
