BT850 Series Bluetooth Module

Recommended for New Design (RND)

Overview

The BT85x series of USB HCI modules and Adapter leverage the Cypress CYW20704 A2 chipset to provide exceptionally low power consumption with 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 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 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. 

Two form factors: BT850 Module or BT851 packaged USB Adapter.
