What Was the First Nintendo DS Model?

The question likely refers to the Nintendo DS handheld family, not Digital Signal Processors.

The first Nintendo DS (codename "Nitro") launched:

• November 21, 2004 (North America)
• December 2, 2004 (Japan)
• March 11, 2005 (Europe)

It featured two screens (bottom touch), Wi-Fi, microphone, GBA cartridge slot, and PictoChat.
