lcd module 20x4 i2c factory

ERM2004SYG-2 is 20 characters wide,4 rows character lcd module,SPLC780C controller (Industry-standard HD44780 compatible controller),6800 4/8-bit parallel interface,single led backlight with yellow green color included can be dimmed easily with a resistor or PWM,stn-lcd positive,dark blue text on the yellow green color,wide operating temperature range,rohs compliant,built in character set supports English/Japanese text, see the SPLC780C datasheet for the full character set. It"s optional for pin header connection,5V or 3.3V power supply and I2C adapter board for arduino.

20×4 LCD Display with IIC/I2C interface (Soldered) is used to visualize your sensor data or to display a message to the user. This 20×4 LCD Display has 4 Rows of 20 Character Column (i.e each row has 20 character can be displayed).

This display comes with I2C Attached to reduce the no. of pins utilized on a microcontroller. In I2C the data sent serially and using Shift register the data will be converted to parallel that an LCD Accepts. So it is very handy and drastically reduce the pins utilization to just 4 pins VCC, GND, SCL and SDA Pins. Hence you have more room to connect multiple sensors or actuators to the Arduino or any other microcontroller.Model: LCD2004

This module realizes a fast I2C interface with the familiar LCD displays (16x02, 16x04 and 20x04), which makes the control of these displays much easier and more economical with I / O pins.

Because this module has 8 options for the address (0X20-0X27), it is possible to control 8 of these interface modules simultaneously with only 2 connections. By means of the built-in potentiometer on this module it is possible to adjust the backlight and contrast of the LCD.

This LCD module utilizes an I2C module to reduce the number of wiring in the system. An I2C device sends and receives data serially from the I2C bus. Implementing an I2C device requires some knowledge about addressing and framing the serial data in order to avoid data collision. The I2C MCU is accessible at address 0x27 by default; although it can be modified by soldering the A0, A1 and A2 jumpers on the I2C backpack PCB.
