Xiaomi's second-gen TV Box S is a Google TV set-top box that outputs up to 4K at 60Hz through an HDMI 2.1 port — though its bandwidth is 2.0-class, so don't expect 4K@120Hz gaming. It adds a single USB 2.0 Type-A port for storage and a combined AV/SPDIF 3.5mm jack for legacy composite video and optical audio. Power arrives through a DC barrel from the bundled adapter rather than USB-C. Below is every port and the cable you need to connect it.

Notes & Compatibility
HDMI carries the ‘2.1’ label but delivers 2.0-class 4K@60 bandwidth (no 4K@120). The rear 3.5mm jack is a combined AV + optical S/PDIF output — kept in prose, not modeled as a discrete palette connector. Powered by an AC adapter into a DC barrel input, which is not modeled.
