CBC-2 01 Amulet

GEMboard Display Controller Board Controller Board Introduction: GEMboard (CBC-2) is a production display controller board for many popular LCD panels ranging from 5.7 to 10.4 with resolutions up 640x480 (VGA). GEMboard affords greater speed in prototyping, maximizes design CBC-2 01 flexibility while shortening the time to market. GUI integration has never been easier. The CBC-2 02 GEMboard contains the complete bill of material including support for backlight (LED or CCFL) and touch panels.
