IIC SERIAL I2C 1602 2004 LCD ADAPTER BOARD FOR ARDUINO

IIC Serial I2C 1602 2004 LCD Adapter Board for Arduino

This IIC Serial I2C LCD Adapter Board, can be connected to a standard HD44780 compatible 16×2 or 20×4 Character Display Module that supports 4 bit mode. All Character Modules sold on our site support 4 bit mode, and nearly all commercially available 16×2 and 20×4 line character modules support it too.

This board has a PCF8574 I2C chip that converts I2C serial data to parallel data for the LCD display. There are many examples on internet for using this board with Arduino. Do a search for “Arduino LCD PCF8574”. The I2C address is 0x3F by default, but this can be changed via 3 solder jumpers provided on the board. This allows up to 3 LCD displays to be controlled via a single I2C bus (giving each one it’s own address).

Features IIC/I2C :

Arduino 1602 I2C interface 4-wire 1602 screen.
IO port of Arduino control board is only 20, so IO ports is not enough for many sensor, SD card, relay modules.
The original 1602 screen need 7 IO ports to drive up, and this module can save 5 IO ports
This is another great IIC/I2C/TWI/SPI Serial Interface. With this I2C interface module, you will be able to transfer data via only 2 wires. If you already have I2C devices in your project, this LCD module actually cost no more resources.
I2C Address: 0X20~0X27 (the original address is 0X20,you can change it yourself)
Supply voltage: 5V
The backlight and contrast is adjusted by potentiometer
Come with 2 IIC interface, which can be connected by Dupont Line or IIC dedicated cable
Compatible with 1602 LCD
