What it does

The LCD 16×2 with I2C Soldered Display combines a standard 16×2 character LCD with a pre-soldered PCF8574 I2C backpack. It requires only 2 data pins (SDA/SCL) for communication, freeing up valuable GPIO pins on your microcontroller.

Key features

  • 16×2 character display with pre-soldered I2C backpack
  • I2C interface uses only 2 pins (SDA + SCL)
  • PCF8574 I2C expander built-in
  • Adjustable I2C address (usually 0x27 or 0x3F)
  • Backlight control via I2C
  • Contrast adjustment potentiometer on backpack

Good to know

  • Install LiquidCrystal_I2C library – check I2C address
  • Common addresses: 0x27, 0x3F – scan with I2C scanner if unsure
  • Backlight can be controlled on/off via library function
  • Adjust contrast pot on backpack if display is blank
  • I2C speed: 100kHz standard, can try 400kHz for faster updates
