Nintendo Switch 2 mystery accessory: Possible cube-like dimensions and UMPC design raise questions regarding functionality

Following previous leaks about a mysterious accessory for the upcoming Nintendo Switch 2, analysis of its FCC documents have now led to some more clarity on the nature of the device, labeled as CLO-001.

The earlier leak hinted at its use of a 24 GHz millimeter-wave sensor, but these new filings focus more on its size, shape, and potential purpose (though we may be far off when the device is actually unveiled). Measuring approximately 90.6mm x 90.6mm x 83.7mm (like a Gamecube, but smaller), the accessory is classified as a "wireless device," which differs from the typical, more specific terminology Nintendo uses - like "game console" or "controller". If you're wondering how the dimensions were discerned, here's a statement from the source leak:

The dimensions should be approximately 90.6mm x 90.6mm x 83.7mm (width x height x depth) give or take a little bit for plastic etc. This was calculated with antenna placement measurements. For example the 24GHz antenna is 10.5mm from the Top edge and 80.05mm from the bottom edge, giving us a total height of 90.6mm.

As mentioned above, the CLO-001 features a 24 GHz antenna that extends 10.55mm from the top - hinting at its intended signal range and configuration. Listed as a portable Ultra Mobile PC (UMPC)-like device as per the given leak, it could include a rechargeable battery (contrary to what was rumored before). If this is true, it would likely make it fully operational without external power. This classification suggests that it may not be just an accessory but a standalone unit or something beyond just game functionality. Furthermore, UMPC devices according to the FCC have some type of screen, as the leak suggests - so there might be a screen or glass on the front of the device.

While the exact purpose of this device is still elusive, there is ongoing speculation that it could be integrated with the Switch successor to upgrade its gameplay capabilities somehow. Testing for radiation absorption rates further suggests the CLO-001 could be designed for handheld use.

Online communities like Reddit have had all sorts of theories - from its potential use as an alarm clock or a small-screen controller to suggestions of an augmented reality (AR) gaming accessory. However, until more official details emerge, these ideas should be taken with a grain of salt - especially since Nintendo hasn't even made an official statement regarding the follow-up to the Switch (currently $289.99 on Amazon) in a while now.
