Description :
1. The real 5.4 Bluetooth chip is adopted, which conforms to the technical specification of Bluetooth 5.4, LMP:13.X, BLE/EDR dual-mode low-power transmission.
2. Longer transmission distance: 150m long transmission distance (no barrier), upgraded antenna and strong signal.
3. More stable transmission rate: 3Mbps transmission rate, providing high-speed file and audio data transmission.
4. Drive-free use: it supports plug-and-play without drive, without CD installation, which is convenient and simple. (Win8.1/10/11 is free of drive, and Win7 needs to install a driver)
5. Ultra-low delay speed link, intelligent sleep wake-up to save energy, 24-bit CRC check to resist interference, adaptive frequency hopping to reduce crosstalk.
6. backwards compatibility Bluetooth 2.0, Bluetooth 2.1, Bluetooth 3.0, Bluetooth 4.0, Bluetooth 5.0, Bluetooth 5.1, Bluetooth 5.3 and other specifications.
7.USB2.0 interface (universal USB3.0).
8. It can connect 7 kinds of devices at the same time with strong compatibility, and realize the wireless Bluetooth connection between the computer and other Bluetooth protocol devices (Bluetooth headset/speaker/mouse/keyboard/gamepad/mobile phone/printer, etc.) for audio, data and image transmission.
9. Technology upgrade, one link, and subsequent use of automatic reconnection, without secondary pairing.
