Ugreen USB-A Bluetooth 5.4 Adapter CM748 Product Overview
The Ugreen USB-A Bluetooth 5.4 Adapter CM748 is a high-performance wireless dongle designed to bring modern, low-latency connectivity to desktop computers and laptops. This professional-grade active adapter updates systems lacking native wireless chipsets, enabling seamless interaction with modern Bluetooth peripherals. Engineered with an ultra-compact form factor, it offers an efficient and clean hardware solution to modernize office setups, gaming rigs, and media workstations.
Core Features and Technical Specifications
Next-Generation Bluetooth 5.4 Architecture
Built around the advanced Actions ATS2851 processing chipset, this adapter implements the latest Bluetooth 5.4 protocol. This standard optimizes signal density, speeds up device reconnection cycles, and drastically lowers latency compared to older Bluetooth standards. It provides a maximum data transfer rate of up to 3Mbps, ensuring uncompressed audio streams and fast file transfers.
Extended 20-Meter Wireless Coverage
Equipped with a high-performance internal antenna operating in the 2400MHz to 2483.5MHz frequency range, the adapter delivers a stable wireless range of up to 20 meters in open, unobstructed environments. This long-range capability allows users to move freely around a workspace or streaming studio without experiencing audio cutouts or peripheral disconnections.
Multi-Device Simultaneous Synchronization
The Ugreen hardware controller supports simultaneous active connections for up to five distinct Bluetooth devices. Users can pair wireless headphones, a game controller, a mechanical keyboard, a precision mouse, and a Bluetooth printer at the exact same time without channel crosstalk or data interference.
Ultra-Compact Plug and Forget Profile
The adapter features an ultra-small physical footprint measuring approximately 26mm by 14mm by 7mm. When inserted into a standard USB-A port, it sits nearly flush against the host machine chassis. This design prevents accidental physical damage to the USB port and keeps adjacent ports accessible for other peripherals.
