Este pequeño modulo permite conectar fácilmente una pantalla LCD alfanumerica convencional a un Microcontrolador o Arduino mediante tan solo 2 cables (I2C). Funciona con pantallas de caracteres (no gráficas) dese 8x1 hasta 20x4 caracteres y soporta una conexión tanto I2C como SPI.

Es especialmente útil si te quedas sin pines disponibles en tu Arduino o microcontrolador y además dispone de una completa librería para Arduino lista para utilizar! Por la parte trasera incluye un potenciómetro para el ajuste del contraste y se incluyen los bornes de conexión (sin soldar).

By using simple i2c and SPI input/output expanders we have reduced the number of pins (only 2 pins are needed for i2c) while still making it easy to interface with the LCD. For Arduino users, we provide a easy-to-use library that is backwards compatible with projects using the '6 pin' wiring. The breakout comes with a 2-pin and 3-pin terminal block as shown (you can snap it together to make a 5-pin terminal and then solder it to the backpack for easy wiring).

This backpack will work with any 'standard' character LCD, from 8x1 to 20x4 sizes! As long as they have a 16-pin single-line connection header at the top. We carry a few LCDs that work great. We suggest using our blue & white 20x4 or 16x2 LCDs. It does not work with the 16x2 OLED displays. 


For advanced users, this project can be used for general purpose I/O expansion, the MCP23008 has 8 i/o pins (7 are connected) with optional pull-ups, the SPI 74HC595 has 7 connected outputs.


Notas:   

  * NO incluye el Display LCD ni la placa Arduino.

  * Este producto es la version original hecho en USA por Adafruit, NO Chino, ademas de incluir una libreria para Arduino y tutorial.
