Arduino IIC/I2C interface was developed to reduce the IO port usage on Arduino board. I2C Address: 0x3F or 0x27 The device address can be modified by connecting: A0/A1/A2. The default is 0x3F or 0x27 (can be obtained by scanning); Address modification instructions (take the default address 0x27 as an example) A0, A1, A2 all disconnected address is 0c27; A0 connection: the address is modified to: 0x26; A1 connection: the address is modified to: 0x25; A3 connection: the address is modified to: 0x23; ...... A0, A1, A2 all links, the address is modified to: 0x20; How to connect: GND: POWER -; VCC: POWER -; SDA: IIC data line; SCL: IIC clock line; Old 1602 screen requires 7 IO ports but this module uses only two. Much needed control panel IO ports can be used to add some sensors, SD card and so on. Package List: 1x IIC/I2C/TWI 1602 Serial LCD Module.
