Does not look like the device shown in ad

This unit works just like any other 2004 I2C LCD. However, unlike every other device I've used, this one has 2 small metal-framed indentations on each side of the display. Build something with multiple LCDs and add it to the project. It doesn't seem to be the same.

Pros

. This is a high performance serial bus with bus rules and fast or low device clocks required for multi-master systems. The I2C bus has only two bidirectional signal lines, the serial data line (SDA) and the serial clock line (SCL).

Cons
