The CLCD interface board provides multiple sockets for different types of CLCD displays and touchscreens. It connects to the PB926EJ-S by a single cable.
The design of the interface board enables you to use to choose the CLCD display that is appropriate for your application. The CLCD displays and touchscreens supported by the interface board are:
Sanyo 3.8 inch QVGA color TFT with touchscreen and fluorescent backlight
