  • Cool LCD display with a high speed I2C serial bus
  • Number of characters: 20 characters x 4 Lines
  • Compatible with both Gadgeteer, Arduino DUE and Arduino UNO/Mega
  • Blue LED backlight with white char color

The DFRobot I2C / TWI 4x20 LCD Module is compatible with Gadgeteer and features a cool LCD display with a high speed I2C serial bus. With the limited pin resources, your project may be out of resources using normal LCD shield. The LCD display is a 4x20 character STN white display with a blue LED backlight. With this I2C interface LCD module, you only need 2 lines (I2C) to display the information. Fantastic for Arduino based project. This board is able to be powered by 5V or 3.3V which make it compatible with both Gadgeteer, Arduino DUE 3.3V system and standard Arduino UNO/Mega 5V system.

Simple and efficient

Very easy to connect thanks to its I2C interface, it was operational less than 5 minutes after receipt of the package

Good product

Very good product delivered on time. Only question to which I did not find an answer in the datasheets .. What is the type of the output connector (4 pins) please ?? Thank you in advance ! -------------------------------------------------- -------------------------------------------------- ---------- Our technical team will contact you soon to answer your question.

easy connection, works as expected

I am just using this as an LCD display, so the cable it shipped with isn't used. To use it, just connect VCC/GND, and SDA and SDL to an Arduino. Download the library in the dfr0154.zip from the link above, and voila. You are up and running. Mine shipped with the i2c address set at 0x27. I've seen some LiquidCrystal_i2c libraries' examples defaulting to 0x20. If yours doesn't work, try 0x27 for the address. I did also try to run it at 3.3v and 5v, both work fine. Although at 3.3v, the pot at the back has to be adjusted all the way to the left, and even then the contrast is not great. At 5v it is beautiful.

Works great

I have purchased several of these displays with I2C, I find them easy to write to and only need two wires!

It just works

Standard libraries and no issues, worked great and very easy to get setup.
