1602 LCD 2004 20x4 i2c LCD Display Adapter IIC//TWI/SPI/I2C Serial Interface Module Shield for Arduino UNO R3 MEGA2560 2 Pcs

Ardest #ad - Handy device for i2c interfacing. If you have some 1602/2004 displays or similar and you don't want to have to use 6 to 12 pins on your Arduino or Raspberry Pi just to drive the display then these are just the ticket.

It saves from having to wire up and uses many gpio pins. If you already have a bunch of the 1602s but they use up a ridiculous number of pins on the Arduino, this LCD module really make interfacing to LCD text displays easy with an arduino. Works fine with the 2004 lcd display as well. The i2c module can drive 2 and 4 line LCD displays for Arduino. Compatible for 1602 lcd. An excellent improvement and conversion for older lcds, and saves a lot of pins on the Arduino.

The i2c interface is a huge improvement, freeing up a lot of pins on the Arduino for additional functionality and including the contrast control and backlight enable/disable. This little i2c interface module works great and only two signal connections are required plus one each for power and ground. Good circuits to reduce the number of connections between your MCU and the LCD.
