The '''NDEV''' ([[RVL Product Codes|product code]] '''RVT-001''') is the main development system for the Wii, taking the form of a black box including full Wii hardware with 192MB of RAM (the retail system has 88MB; the GDDR3 area on the NDEV is expanded from 64MB to 128MB, as with the [[RVT-H Reader]]) as well as debugger, optical disc emulation, and Host I/O hardware.

The NDEV features all the ports and functionality found on a retail system (minus a physical disc drive), as well as 3 additional USB ports and one additional serial (DB9) 115200-baud port. It '''does not have a disc drive or internal hard drive, so all software is read from NAND or the host system. This means that it can only store WiiWare and Virtual Console titles, and not builds of disc games'''. The NDEV cannot boot without an attached host system, and can only launch disc titles if they are served using [[ODEM]] on the host system.

NDEV 1.x were the initial systems used from February 2006 to around June 2006 for internal bringup and third-party game development; there may be some level of discrepancy between those systems used internally and the ones distributed to third-parties, as internal documentation refers to the NDEV 2.0 as the 'main system for game developers' with NDEV 1.x being a bare board intended only for internal bringup, but it is known that some 1.x NDEV units and their associated Revolution SDK (1.0) were briefly distributed to third-party developers.

It's possible that the externally distributed "NDEV 1.x" systems had an NDEV 2 board, as earlier documentation shows that the NDEV 1 and NDEV 2 boards were developed simultaneously, with the NDEV 1 having a completely different board design that wouldn't fit in the NDEV 2 & later's casing, and many additional features meant for internal debugging only.
NDEV 1.x (at least the internal versions) had a number of features not present in 2.0 and later, including:
