2004 lcd module datasheet price

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.

ERM1202SYG-1 is 12 characters wide,2 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.Optional 3.3v or 5v power supply and optional pin header connection.

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.

ERMC1602SBS-2 is 16 characters wide,2 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.

A project I"m working on started with an Arduino so everything was developed around 5V. Now a redesign of the electronics is using 3.3V circuits for 90% of the device, but the 2x16 character LCD modules are still 5V. I contacted the manufacturer and they don"t have a mechanically compatible unit running on 3.3V.

However, the data sheet for the controller chip indicates it runs off any voltage down to 2.7V. So it will work at 3.3V for sure. I guess the issue is the LCD itself may not be suited for 5V. When I"ve looked at LCDs in the past they seem to be made for one or the other voltage. Not sure what they optimize differently. But without simply trying a module on 3.3V (I don"t have one myself), anyone know if these things are actually voltage agnostic?

Then i saw those "A" and "K" one the right side, guess what, I used "A" for 3.3V and "K" for Ground, the back light was on and everything was working fine(except the lost pixels. I really don"t know what cause the LCD to malfunction, I just wont try to power the back light through pins 15-16.

Of course pins 15 and 16 for the backlight have absolutely nothing whatsoever to do with the LCD panel and its operation. What voltage are you powering it with?

This IIC/I2C/TWI Serial 2004/20x4 LCD Module Shield for Arduino Uno/Mega2560 displays white contents on an elegant blue. It can display 4 rows with 20 characters for each. With IIC/I2C interface, it only takes two I/O ports thus saving more for other usages.
