Arduino IIC/I2C/interface LCD1602 pinboard/Arduino function library for free
Package / Case:
"Arduino 1602 I2C interface four line 1602 screen Arduino IIC/I2C interface LCD1602 pinboard(excluding LCD screen) Arduino control board has only 20 interfaces, such limited number restricts the connection of relay module, sensor, SD card and etc. The original 1602 screen needs seven IO interface to be driven while our module needs only 2. We will give away Arduino function library Specification： 1. supply voltage: +5V 2. Support I2C protocol 3. Equipped with backlight and potentiometer for contrast adjustment 4. 4-line output for the convenience of users 5. Device address:0*27 "
