SMA C02#Q2312_B Bluetooth 5.3 USB Adapter

This USB adapter adds Bluetooth 5.3 capability to Windows 11, 10 and 8.1 PCs and laptops that lack built-in Bluetooth. It uses a Realtek chip with dual-mode operation and an external 5dBi antenna. The device is not compatible with Mac, Linux, TVs, car stereos or 2.4 GHz wireless peripherals.

Range and simultaneous connections

Class 1 radio technology delivers an open-area range of up to 100 m or 150 m, reaching 328 ft to 492 ft in clear conditions. The adapter supports up to five Bluetooth devices at once, such as headphones, speakers, keyboards, mice, smartphones or printers. Backward compatibility covers Bluetooth 5.2 down to 1.1.

Thermals, noise and power draw

Bluetooth 5.3 with Enhanced Data Rate and Low Energy reduces power consumption and latency during transfers up to 3 Mbps. The dongle has no moving parts, so it runs silently and adds negligible heat to a USB port. Driver-free installation on supported Windows versions keeps system overhead minimal.

Questions about this item

Will the Bluetooth 5.3 adapter connect with my existing Bluetooth 5.2 headphones and keyboard?

Yes, it is backward compatible with Bluetooth 5.2 and earlier versions, so your current peripherals will pair and work normally.

How can I verify the Realtek chip is delivering the promised 3 Mbps transfer rate after installation?

Check the adapter properties in Windows Device Manager to confirm Bluetooth 5.3 enumeration, then monitor throughput during a file transfer to a paired device.

Does the package include the 5 dBi external antenna or must it be purchased separately?

The enhanced 5 dBi external antenna is built into the dongle; nothing extra is required for the stated 150 m open‑area range.
