Single LED backlight with a resistor included, you can power it directly from 5V. If it’s too bright for you, it can be dimmed easily with a resistor or PWM and uses much less power than LCD with EL (electroluminescent) backlights

RC2004A is 20 characters x 4 lines monochrome LCD display module. The RC2004A LCD display has the same specs as RC2004A1. The only difference between them is the position of pins. RC2004A has 16pins on the PCB; pins of RC2004A1 are on the FFC connector. Default interface of RC2004A LCD display is 6800 with built-in IC ST7066; if you require interface such as SPI or I2C, they’re available as well, but the IC will be replaced with RW1063. Power supply of LCD display RC2004A is 5V (3V is optional). Negative voltage version is available for 3V power supply.

There are many LCD modes to choose from, including STN negative, blue ; STN positive, gray/yellow-green ; FSTN positive, white ; FSTN negative, black. RC2004A display LCD 20x4 offers a selection of fonts, for instance, English/Japanese, Europe and Cyrillic (Russian), etc. If you’d like to obtain full datasheet of LCD 20x4, please contact us for more info!

LCD modules are very commonly used in most embedded projects, the reason being its cheap price, availability, and programmer-friendly. Most of us would have come across these displays in our day to day life, either at PCO’s or calculators. Alphanumeric Graphical LCD (2004A) is a 20x4 Blue Coloured Liquid Crystal Display. It can display 4 lines of text and each line can have up to 20 characters in it, which is bigger than the 16x2 LCD displaybut the programming is almost same. These characters can either be text, numbers, graphical symbols or even custom characters. It can be used in DIY projects, to display the data on IoT projects, etc.

We know that each character has 40 Pixels and for 80 Characters we will have 3200 Pixels. Further, the LCD should also be instructed about the Position of the Pixels. It is a hectic task for the microcontroller, hence Driver IC like ST7066 is used, which is mounted on the backside of the LCD Module.it takes data from the Microcontroller and processes them to display on the LCD Screen. You can use it in 8 bit parallel interface or 4 bit parallel interface mode if you need to connect fewer lines to the microcontroller.

There are not many differences between the two LCD screens apart from the obvious one that 16*2 can display only 32 characters and 20*4 can display 80 characters. So you have to choose the display according to your needs. If you need a display to show a lot of data then go for 20*4 size and if there is not too much of data to display then go for 16*2 LCD. It also depends on the packaging size of your project. If space is at a premium then go for smaller sized 16*2 else its 20*4.

ERM2004SBS-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 white color included can be dimmed easily with a resistor or PWM,stn- blue lcd negative,white text on the blue 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.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!".For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and Development Kit at the bottom of this page.

This is a 20x4 Arduino compatible LCD display module with high speed I2C interface. It is able to display 20x4 characters on two lines, whitecharacterson blue background.

Generally, LCD display will run out of Arduino pin resource. It needs 6 digital pins and 2 power pin for a LCD display. If you want to build a robot project, it will be a problem with Arduino UNO and LCD display.

This I2C 20x4 LCD display module is designed for Arduino microcontroller. It is using I2C communication interface, With this I2C interface, only 2 lines (I2C) are required to display the information on any Arduino based projects. It will save at least 4 digital / analog pins on Arduino. All connector are standard XH2.54 (Breadboard type). You can connect it with jumper wire directly.

This 1602 LCD module has 8 I2C address in all, from 0x20 to 0x27. You can set one according to your requirements, avoiding the confliction of I2C address. And its contrast can be adjusted manually.

Features：IIC/I2C interface was developed to reduce the IO port usage on Arduino board.* Old 1602 screen requires 7 IO ports but this module uses only two.* Much needed control panel IO ports can be used to add some sensors, SD card and so on.* A New High-Quality 4 Line 20 Character Lcd Module.* Potentiometer can be adjusted to control the contrast.* Back light can be turned off by removing the jumper on the back panel.Specification:* Interface: I2C* I2C Address: 0x27* Pin Definition : GND、VCC、SDA、SCL* Back lit (Yellow with Black char color)* Supply voltage: 5V* Size : 60mm×99mm* Contrast Adjust : Potentiometer* Backlight Adjust : Jumper

This the larger version of our 16x4 LCD display. Its 24 character by 4 line display has a very clear and high contrast white text upon a blue background/backlight. It also includes a serial I2C/IIC adaptor board pre-soldered to the back of the LCD. This means it can be controlled with just 2 I2C serial data pins (SDA & SCL) and so requires far less digital IO pins when controlled from a microcontroller. In total the module only requires 4 wires including 5V power and GND. Contrast adjustment is also provided by the daughter board via a potentiometer. If you plan to use this with an Arduino board you can download a compatible library and example sketch from our support forum here.

These modules are currently supplied with a default I2C address of either 0x27 or 0x3F. To determine which version you have check the black I2C adaptor board on the underside of the module. If there a 3 sets of pads labelled A0, A1, & A2 then the default address will be 0x3F. If there are no pads the default address will be 0x27.

It is possible for the I2C daughter board to bend and come in contact with the LCD module if enough pressure is applied to it. Please ensure when the LCD is installed in your application that no external object is applying pressure to the back of the module.

4 line, 20 positions alphanumeric Standard LCD 20×4 with HD44780 (or compatible) display controller and the standard 4/8 bit parallel interface. The optional available I2C interface fits right on the back of the display and turns its interface from parallel to simple 2-wire I2C (perfect for microcontrollers like Arduino to save on I/O ports).

Standard LCD 20×4 (2004A) green LCD character display with bright yellow LED backlight, high contrast, and optional serial interface (I2C, SDA/SCL) for microcontrollers. The display needs a 5V power supply for operation. With the I2C interface installed on the backside of the Standard LCD 20×4, the backlight can be controlled by software as well. Many different libraries for different programming languages and controller families are available, also countless examples.

An LCD display that can display a max of 20x4 charactors. with the help of the I2C bus convertor and related libraried, you can easily use this module with just 2 wires.
