The BT85x series of USB HCI modules and Adapter leverage the Cypress CYW20704 A2 chipset to provide exceptionally low power consumption with an outstanding range for OEMs needing both Classic Bluetooth and Bluetooth Low Energy support. The Bluetooth 5 core specification shortens your development time and provides enhanced throughput, security and privacy. The BT850 modules are ideal when designers need both performance and minimum size. For maximum flexibility in integration, they support a host USB interface, I2S and PCM audio interfaces, GPIO, and Cypress' GCI coexistence (2-Wire). The modules provide excellent RF performance and identical footprint options for an integrated antenna or an external antenna via a trace pin.

These modules present a Bluetooth standard HCI interface with native support for Windows, Linux, and Android Bluetooth software stacks for operating system-backed devices. The BT851 Pluggable USB Adapter simply plugs into any Windows, Android, or Linux device via an external USB connection. Additionally, Laird has partnered with SEARAN for support of their ultra-small, flexible ‘dotstack’ platform for embedded Cortex M3 and M4 implementations. 


  • Support for Windows/Linux/Android via USB interface, plus external USB pluggable adapter variant.

  • Class I +8dBm output power in an 8.5 x 13 mm package means no need to compromise one for the other

  • A wide array of Operating System support, as well as embedded MCU support for Searan’s flexible DotStack platform, give you even more design choices

  • Certifications and approvals for FCC (USA), ISED (Canada), EU (Europe), Giteki (Japan), RCM (AUS/NZ), Bluetooth SIG

  • Industry-recognized integration and support organization dedicated to reducing your time to market
