Product Description

IIC/I2C / interface, LCD1602/2004 adapter plate for Arduino   

1602 I2C interface 4 line 1602 screen

4, line screen 1602 Arduino 1602 I2C interface
The Arduino IIC LCD1602 / I2C interface adapter plate without LCD screen
The Arduino board IO mouth only 20, add some sensors, SD card, relay module, etc. IO mouth is not enough,
1602 screen need seven IO mouth to drive up, we developed this module can help you save five IO port, we can give the arduino function library
