Compact USB Bluetooth 4.0 adapter

The Shenzhen Sengulink H-161 adds wireless connectivity to a desktop or laptop through a standard USB port. It uses a CSR8510 chip to implement Bluetooth 4.0 and remains compatible with Bluetooth 2.0 and 2.1 devices. The dongle measures 2.20 x 2.00 x 0.50 cm and weighs 0.026 kg, so it stays unobtrusive when plugged in. A driver CD is included for systems that need manual installation.

Low-energy radio with 3 Mbps throughput

The adapter draws between 1.2 V and 3.6 V I/O and supports adaptive frequency hopping plus a 24-bit CRC checksum to reduce interference. Stated transfer rate reaches 3 Mbps, suitable for audio streaming and file transfers. In open air the signal reaches 20m to 50m without blocking, while ultra-low latency and intelligent wake-up keep power draw minimal during idle periods.

CSR Harmony software stack included

Management is handled by the CSR Harmony software suite, which provides multi-language support and multiple application extensions. This software layer determines which profiles and advanced features are available on the host operating system. Buyers who need a different software stack or native driver support without extra utilities should verify compatibility before purchase.

Questions about this item

How do I install the H-161 Bluetooth dongle on a PC?

Insert the USB dongle into an available port, then run the CSR Harmony setup from the included CD to install the driver and management software.

What maintenance will the H-161 adapter need over time?

No scheduled maintenance is required; keep the USB contacts clean and reinstall the CSR Harmony software if a Windows update removes the driver.

What is the first limit I will hit during continuous file transfers?

The 3 Mbps transfer rate caps sustained throughput, so large batches will move at that speed regardless of signal strength.
