StarTech USBA-BLUETOOTH-V5-C2 USB Bluetooth 5.0 Nano Adapter

Overview

The StarTech USBA-BLUETOOTH-V5-C2 is a nano-sized USB-A Bluetooth 5.0 adapter built around the Realtek RTL8761B chipset. At just 0.8 in long and 0.1 oz, it plugs into any available USB 2.0 Type-A port and disappears — adding or replacing Bluetooth wireless capability on desktops, thin clients, embedded PCs, and security workstations where a built-in radio is absent, broken, or simply not on the board. If you manage endpoints that need Bluetooth peripherals (keyboards, barcode scanners, wireless headsets, BLE sensors) and are standardizing across Windows 7 through 11 or Linux 2.6.32+ environments, this adapter handles the job without adding bulk or requiring an external power supply.

Key Features

• Bluetooth 5.0 (Class 2, up to 10m / 33 ft): Class 2 limits the radio to a practical 10-meter working range — enough for desk peripherals, nearby scanners, and BLE devices without broadcasting far enough to become a security surface concern in shared spaces. For warehouse or industrial environments needing 30m+ coverage, Class 1 adapters are the appropriate alternative.
• 2 Mbps Maximum Data Transfer Rate: Bluetooth 5.0 doubles the data throughput available in Bluetooth 4.x at basic rate, which matters when pairing BLE sensors or audio devices that benefit from faster polling cycles. For keyboard/mouse pairs or simple HID devices, you will never saturate this bandwidth.
• Realtek RTL8761B Chipset: The RTL8761B is a well-documented, driver-supported chipset with broad OS coverage. Knowing the chipset matters in enterprise deployments — you can validate driver packages against your OS image before rollout, and the chip has an established Linux kernel driver path (kernel 2.6.32+), which simplifies deployment on Ubuntu, Debian, or RHEL-based security appliances.
• USB 2.0 Type-A Connector — USB-Powered: Draws power directly from the host USB port with no separate supply needed. The Type-A plug means compatibility with virtually every desktop, server, NVR, or industrial PC that has exposed USB headers — no adapter required.
• Nano Form Factor (0.8 in × 0.5 in × 0.2 in, 2.0g): The physical profile is nearly flush to the port when inserted, reducing the chance of accidental snag in rack or kiosk environments. It is not a full-length dongle — there are no status LEDs or protruding housings to worry about in tight enclosures.
• Windows Vista / 7 / 8 / 8.1 / 10 / 11 Support: Covers the full Windows lifecycle including legacy OS versions still found on embedded control panels, older NVR workstations, and industrial HMIs. Plug-and-play on Windows 10/11 means no manual driver hunt for modern machines.
• Linux Kernel 2.6.32+ Support: Directly relevant for security appliance builders and integrators deploying on Linux-based VMS servers or embedded platforms. Verify against your specific kernel and distribution before bulk procurement.
• Operating Temperature 5°C to 50°C (41°F to 122°F): Designed for conditioned indoor environments — control rooms, server rooms, office workstations. Not rated for unheated warehouses or outdoor enclosures where ambient temperatures drop below 41°F.
• 2-Year Manufacturer Warranty: Two years of coverage on a sub-1-oz adapter is standard for the category and appropriate for the use case — most enterprises replace the host device before the adapter reaches end of useful life.

Integration & Compatibility

The USBA-BLUETOOTH-V5-C2 (often searched as USBA BLUETOOTH V5 C2) integrates with any host system exposing a USB 2.0 or higher Type-A port. On Windows 10 and 11, the RTL8761B is recognized without additional driver installation in most configurations. On Windows 7/8 and Linux environments, verify the driver package against your OS image version prior to deployment. The adapter pairs with any Bluetooth 5.0, 4.x, or compatible peripheral — Bluetooth 5.0 maintains backward compatibility with earlier Bluetooth generations, so existing HID peripherals, audio devices, and BLE sensors are supported. For pairing with Bluetooth barcode scanners or wireless input devices on network video recorders and security workstations, the RTL8761B chipset delivers a stable, low-latency connection within the 10-meter operating range. If you are building out a security workstation accessory kit or upgrading thin client endpoints, this adapter pairs naturally with USB hubs or KVM switches that retain USB passthrough. Review your USB connectivity planning guide to confirm port availability on target hardware before ordering in volume.

Frequently Asked Questions

Q: What Bluetooth version does the USBA-BLUETOOTH-V5-C2 support?

A: It supports Bluetooth 5.0 with a maximum data transfer rate of 2 Mbps. It is Class 2, which gives a working range of up to 10 meters (33 feet).

Q: Which operating systems are compatible with the USBA-BLUETOOTH-V5-C2?

A: Windows Vista, 7, 8, 8.1, 10, and 11, plus Linux kernel version 2.6.32 and later. It is not listed as compatible with macOS based on available evidence.

Q: What chipset does the USBA-BLUETOOTH-V5-C2 use?

A: The Realtek RTL8761B. This is a well-documented chipset with established driver support on both Windows and Linux platforms.

Q: Does the USBA-BLUETOOTH-V5-C2 require an external power supply?

A: No. It is USB-powered, drawing power directly from the host USB Type-A port. No separate power supply or cable is required.

Q: What is the warranty on the USBA-BLUETOOTH-V5-C2?

A: StarTech provides a 2-year manufacturer warranty on this adapter.

Q: Is the USBA-BLUETOOTH-V5-C2 suitable for outdoor or unheated environments?

A: No. The operating temperature range is 5°C to 50°C (41°F to 122°F), which is rated for conditioned indoor environments only. Unheated warehouses, outdoor enclosures, or locations where ambient temperatures regularly fall below 41°F are outside the rated operating range.

The USBA-BLUETOOTH-V5-C2 comes up frequently when an integrator is commissioning a security workstation or NVR and discovers the host machine either shipped without onboard Bluetooth or has a failed internal radio. The RTL8761B chipset is the detail I flag first — it has a clean driver path on Linux 2.6.32+ and is plug-and-play on Windows 10/11, which keeps deployment friction low across mixed OS environments.

Technical Highlights:

• Bluetooth 5.0 at 2 Mbps: Doubles the throughput ceiling of Bluetooth 4.x, which matters when polling BLE sensors or pairing devices that push more frequent data packets — even if most HID use cases never saturate it.
• Class 2 Radio, 10m Range: The 10-meter (33 ft) ceiling is deliberate for shared office and control room environments — it keeps the wireless footprint tight and reduces the chance of unintended device pairing across adjacent workstations.
• Nano Form Factor, 2.0g: At 0.8 in × 0.5 in and 2.0 grams, it sits nearly flush in the USB-A port. In rack-mounted or kiosk installations where port clearance is limited, this matters more than it sounds.

Deployment Considerations:

• On Windows 7 and Linux deployments, validate the RTL8761B driver package against your specific OS image and kernel version before rolling out in bulk — plug-and-play is not guaranteed on all legacy configurations.
• The operating temperature floor is 5°C (41°F) — if the host machine lives in an unheated server closet or warehouse edge location that drops below that threshold in winter, this adapter is not the right fit.

This adapter is a practical fit for security control rooms and workstation refreshes where the host machine has an open USB-A port and Bluetooth 5.0 is needed for wireless peripherals — particularly on Windows 10/11 machines where the RTL8761B installs without manual driver work.
