IIC Serial I2C 1602 2004 LCD Adapter Board for Arduino
This IIC Serial I2C LCD Adapter Board, is 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 the internet for using this board with Arduino. Search “Arduino LCD PCF8574”. The I2C address is 0x3F by default, changed via 3 solder jumpers provided on the board. up to 3 LCD displays to be controlled via a single I2C bus (giving each one its own address).
Features IIC/I2C :
- Arduino 1602 I2C interface 4-wire 1602 screen.
- The IO port of the Arduino control board is only 20, so IO ports are not enough for many sensors, SD cards, and relay modules.
- The original 1602 screen needs 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 costs no more resources.
- I2C Address: 0X20~0X27 (the original address is 0X20,you can change it yourself)
- Supply voltage: 5V
- potentiometer adjusts the backlight and contrast is
- Come with 2 IIC interface, connected by Dupont Line or IIC dedicated cable
- Compatible with 1602 LCD
