3.4.4 Liquid Crystal Display (LCD) Interface

The SAM9X60-Curiosity board provides a connector with 24 bits of data and control signals to the LCD interface.

Optional displays such as AC320005-5 (refer to the product web page) can be connected to the board.

In order to operate correctly with various LCD modules, two power supplies are available: 3.3V and 5 VDC (default). The selection is made with 0R resistors.

J13 is a 1.27-mm pitch, 50-pin header. It gives access to the LCD signals.
