This document describes key hardware aspects of the Laird BT85x Bluetooth HCI module and Adapter . This
document is mainly intended to assist device manufacturers and related parties with the integration of this
module into their host devices. Data in this document are drawn from several sources including data sheets for
the Cypress CYW20704A2.
Because the BT850-Sx is currently in development stage, this document is preliminary and the information in
this document is subject to change. Please contact Laird Technologies or visit the

ESCRIPTION
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 v4.2 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, I
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 with inbuilt
Bluetooth stack simply plugs into any Windows, Android or Linux device via external USB connection.
Additionally, Laird has partnered with
embedded Cortex M3 and M4 implementations.
