* Weight: 300 grams (9.7 oz).
* Physical dimensions: 148.7 mm x 84.7 mm x 28.9 mm (5.85 in x 3.33 in x 1.13 in).
* Screens: Two separate 3-inch TFT LCD, resolution of 256 x 192 pixels, dimensions of 62 mm x 46 mm and 77 mm diagonal, and a dot pitch of 0.24 mm. The gap between the screens is approximately 21 mm, equivalent to about 92 "hidden" lines. The lowermost display of the Nintendo DS is overlaid with a resistive touch screen, which registers pressure from one point on the screen at a time, averaging multiple points of contact if necessary.
* CPUs: Two ARM processors, an ARM946E-S main CPU and ARM7 co-processor at clock speeds of 67 MHz and 33 MHz respectively. The ARM946E-S CPU processes gameplay mechanisms and video rendering while the ARM7TDMI processes sound output, Wi-Fi support and additionally, when in Game Boy Advance mode, processes what the other processor used to do.
* RAM: 4 MB of Mobile RAM.
* Voltage: 1.65 volts required.
* Storage: 256 kB of Serial Flash Memory.
* Wireless: Built-in 802.11 Wireless Network Connection (802.11b compatible with WEP encryption support only).
The system's 3D hardware performs transform and lighting, texture-coordinate transformation, texture mapping, alpha blending, cel shading, and z-buffering; however, it uses point (nearest neighbor) texture filtering, leading to some titles having a blocky appearance. Unlike most 3D hardware, it has a set limit on the number of triangles it can render as part of a single scene; the maximum amount is about 6144 vertices, or 2048 triangles per frame. The 3D hardware is designed to render to a single screen at a time, so rendering 3D to both screens is difficult and decreases performance significantly. The DS is generally more limited by its polygon budget than by its pixel fill rate. There are also 512 kilobytes of texture memory, and the maximum texture size is 1024x1024 pixels.
The system has 656 kilobytes of video memory and two 2D engines (one per screen). These are similar to (but more powerful than) the Game Boy Advance's single 2D engine; however, the cores are divided into the main core and sub core. Only the main core is capable of vertex 3D rendering.
The Nintendo DS has compatibility with Wi-Fi (IEEE 802.11b). Wi-Fi is used for accessing the Nintendo Wi-Fi Connection, compete with other users playing the same Wi-Fi compatible game, Pictochat or with a special cartridge and RAM extension, browse the internet.
 Media specifications
Nintendo DS games use a proprietary solid state ROM "game card" format resembling the memory cards used in other portable electronic devices such as digital cameras. It currently supports cards ranging from 64–4096 Megabits (8-512 Megabytes) in size. The cards usually have a small amount of flash memory or an EEPROM to save user data such as game progress or high scores. However, there are a small number of games that have no save memory such as Electroplankton. The game cards are 33.0 mm × 35.0 mm × 3.8 mm (about half the breadth and depth as Game Boy Advance cartridges) and weigh around 3.5 grams (1/8 oz).
Nintendo's own custom firmware boots the system. A health and safety warning is displayed first, then the main menu is loaded, similar to the Wii console. The main menu presents the player with four main options to select: play a DS game, use PictoChat, initiate DS Download Play, or play a Game Boy Advance game.
The firmware also features an alarm clock, several options for customization (such as boot priority for when games are inserted and GBA screen preference), and the ability to input user information and preferences (such as name, birthday, favorite color, etc.) that can be used in games.
 Battery life
The Nintendo DS contains a rechargeable lithium-ion battery with a capacity of 850 mAh. On a full four-hour charge, the factory 850 mAh battery lasts about 10 hours. Battery life is affected by multiple factors including speaker volume, use of one or both screens, back lighting, and use of wireless connectivity. The biggest effect on battery life is caused by using the backlight, which can be turned off in the main menu screen, or in selected games (such as Super Mario 64 DS). The battery is designed to be removed only when it expires.
To sustain battery life in the midst of a game, users can close the Nintendo DS system, putting the DS in sleep mode that also pauses the game that is being played; however, closing the system while playing a Game Boy Advance game will not put the Nintendo DS into sleep mode; the game will continue to run normally, including the back light.
