Taiwan’s NCC published the test results of Switch 2 devkit BEE-056, including the NDK Box Black BEE-053 (a.k.a. Relay Box), and AFAIK previously unseen NDK Box White BEE-052.




NDK Box Black BEE-053 features an AC in, a “PC” port (looks like USB-C), an HDMI port, an Ethernet port, a connector to BEE-056 console. This box seems primarily for working with dev tools on PC.



NDK Box White BEE-052 features an AC in, an HDMI port, an Ethernet port, a connector to BEE-056 console, and two USB-A ports. This box seems mainly for testing compatibility with the Dock and USB accessories.



Note the proprietary connector on NDK Boxes, BEE-056 (img 1 below), and custom cable BEE-054 (img 2).


As mentioned before, if Nintendo actually wanted to “block” 3rd party docks, they could’ve easily used a proprietary port and encrypted the communication. Linus’ and The Verge’s allegations of such were a manufactured outrage.
Note: NCC website doesn’t provide direct links, so go to nccmember.ncc.gov.tw and search for “BEE-056”.
