Very simple to use high brightness display.

Just make sure to download the sku.216865.rar and use the provided LiquidCrystal_I2C library as some of the other libraries available on the net are not compatible with this display.

You can make an Arduino project very quickly and since it uses the I2C you won't loose any of the data pins.
Also, you can choose the "I2C address" so you can link multiple displays to the same Arduino board.

Note : it comes with the I2C module not soldered on the LCD (as visible in the photo) but it's easy to solder it on.
