Identify your Apple TV model - Apple Support

“A1625” is Apple TV HD. It has a USB-C port on the back.

“A1842” or “A2169” is Apple TV 4K. It lacks a USB port on the back.

This model number would be on the bottom of the device, on the package box, and also in the menus: Settings﹥General﹥About﹥Model﹥.
