Fantástica pantalla LCD con un bus serie I2C de alta velocidad
Número de carácteres: 20 carácteres x 4 líneas
Compatible con Gadgeteer, Arduino DUE y Arduino UNO / Mega
Luz de fondo LED azul con color blanco
El Módulo LCD DFRobot I2C / TWI 4x20 es una pantalla LCD genial con un bus serie I2C de alta velocidad compatible con Gadgeteer. Con recursos de pin limitados, es posible que su proyecto no tenga recursos suficientes usando una pantalla LCD normal. La pantalla LCD es una pantalla STN blanca de 4x20 carácteres con una luz de fondo LED azul. Con este módulo LCD de interfaz I2C, solo necesita 2 líneas (I2C) para visualizar la información. Fantástico para proyectos basado en Arduino. Esta placa puede funcionar con 5 V o 3,3 V, lo que la hace compatible tanto con el Gadgeteer, el sistema Arduino DUE 3.3V y el sistema estándar Arduino UNO / Mega 5V.
J'ai acheté plusieurs de ces écrans avec I2C, je les trouve faciles à écrire et je n'ai besoin que de deux fils!

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

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!
