Technical Specifications
A 133MHz ARM processor is at the heart of the Nintendo DSi, an improvement on the 67 MHz ARM processor in the DS Lite. The memory is also higher than the DS Lite's 4MB of RAM; the DSi comes in at 16MB of RAM. In terms of display, the DSi is no different from its predecessor. The resolution is 256 by 192 pixels and the screen is TFT LCD with 260,000 colors.
Dimensions
The DSi is larger than its predecessor in terms of height and width but slightly thinner. Overall it stands at 5.4 inches by 2.9 inches by 0.7 inches. The two 3.3 inch screens are slightly bigger too. The stylus, which is the object you use to control DS games with the touch screen, is longer, at 3.6 inches. The name of the product tells you that the DS Lite prides itself on its lack of weight, but the DSi outdoes it in this respect. This handheld console weighs in at 7.5 ounces, including the battery pack.
Battery
The battery in the DSi takes 2 hours 30 minutes to fully charge when flat, which is 30 minutes faster than the DS Lite. A fully charged DSi will take up to 14 hours to drain on the lowest screen brightness setting and up to 4 hours on the highest setting. This battery life is weaker than that of the DS Lite.
Compatibility and Connections
Just like its predecessor, the DSi has a socket for head phones or microphones and an SD memory card slot. Unlike the DS Lite, the DSi does not have a slot for Game Boy games and is not compatible with any Game Boy software.
Camera
The standout new feature for the Nintendo DSi is the addition of cameras. Two digital cameras are now built into the device, one of which has VGA resolution. Any pictures that you take can be sent to your PC, cell phone or another DSi if desired.
