There are many wireless mice in the market, but most of them are pre-paired, and it seems like they have been unified, and the chip model won't be disclosed to you.

Generally, wireless mice meet the following requirements:

1. Range greater than 10 meters (around 20 meters outdoors).
2. 16-channel adaptive bi-directional frequency hopping technology with strong anti-interference performance.
3. Various pairing options like close-range single-side pairing, button pairing, etc.
4. Three-stage power-saving mode, extremely power-efficient.
5. Built-in low battery alarm function (no need for external hardware support).
6. Supports computer sleep wake-up and mouse self-wake-up.
7. No need for any modifications, supports various sensor placement orientations for the casing.
8. VID/PID can be changed according to customer needs.
9. Supports up to 9 buttons.
10. Compatible with sensors such as 5030, 5090, 16083, and can be directly replaced PIN TO PIN.
11. Supports USB 1.1 and USB 2.0.
12. Supports tilt-wheel function.
13. Compatible with Microsoft Win98: 2K; XP; VISTA, Win7, Linux, macOS, and other systems. Provides full software, hardware support, and production support. Can also provide PCBA boards according to customer needs.
