This is an I2C device that can be used as a user interface to a microcontroller with I2C, that is nearly all of them. There are libraries for the ByPic, Arduino and Raspberry Pi in the link below.

There is a 5V and 3.3V I2C interface. The display will work with either 5V or 3.3V

The display has 3 built in fonts and can render 8 lines of 21 characters in font 1 giving a useful amount of information. The input uses a rotary encoder which is much better than buttons particularly if there is a lot of information. The encoder has a switch and also there is a spare button.

The display can also render static images.

The whole assembly is quite thin approximately 5mm

If used in a project box it leaves plenty of room for other equipment.
