IIC I2C Serial Interface Board Module LCD1602 Address Changeable Arduino 1602/2004 I2C Interface 4-Wire 1602/2004 screen
Arduino IIC/I2C Interface LCD1602/2004 adapter plate without LCD screen
Arduino control board IO port is only 20, plus some sensor, SD card Han, relay modules and more, IO port is not enough,
The original 1602/2004 screen requires 7 IO port can drive up, we have developed this module can help you save five IO ports, we send Arduino library
