The standard resolution of 320x240 means it will be quick to update even from the less powerful Arduino. It features a resistive touch screen, micro-SD card slot, a 4MB flash memory and optional PWM control for the backlight. With all these features enabled there are still 11 pins free on the Arduino header.
It is compatible with 3.3V and 5.0V logic, which mean you can use directly without hockup wire or soldering on most devices which has a Arduino pin header.
