Components: 16x2 1602 LCD display + I2C series interface backpack; 1602 LCD display can display 2 x 16 characters with standard HD44780 LCD controller.
Default address: 0x27 for PCF8574T chip; 0x3F for PCF8574AT chip; check which chip you have on the i2c interface. (Before uploading the code to the control board, download the LiquidCrystal_I2C library)
Four pins: VCC, GND, SDL and SCA used to connect Dupont Line or IIC dedicated cable.
Compatibility: Used to connect Arduino and Raspberry pi and can be used to display the clock in real time, temperature, humidity, etc. (You also need a potentiometer to adjust the contrast. Operating voltage: only 5 V.
Wide application: commonly used in copiers, fax machines, laser printers, industrial testing equipment and network equipment such as routers and storage devices.
