It is a touchscreen monitor shield which can be use with many Arduino models ( such as UNO and Leonardo) with resistive 320x240 resolution.With its inner controller it has the ability of sensing more precision touches from analog inputs. It has Micro SD card slot. Hereby you can display images in your micro SD card on monitor easily. Monitor communicates with Arduino through SPI interface. Back lighting can be programmed.
