BT86x - Bluetooth v4.2 UART HCI modules

Classic Bluetooth and Bluetooth Low Energy (BLE) UART HCI modules, supporting a host UART interface

The BT86x series of UART HCI modules utilise 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 BT860 modules are ideal when designers need both performance and minimum size. For maximum flexibility in integration, they support a host UART 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 support for Linux / Android and Embedded Bluetooth software stacks for operating system backed devices. Additionally, Laird has partnered with Searan for support of their ultra small, flexible 'dotstack' platform for embedded Cortex M3 and M4 implementations.

Laird's Development Kit (DVK-BT860-Sx) provides a platform for rapid prototyping of BT860 series modules. The development board provides simple, easy to use access to the various hardware interfaces and configuration options for the module. The DVK is the perfect platform to provide for early development testing of the BT860 module series features and functionality, prior to designing the module onto a host PCB.

DVK-BT860-SAEach DVK-BT860 includes:

Development motherboard The motherboard has the appropriate BT860 module already soldered down onto it and all available hardware interfaces are exposed.
USB Cable - USB A type male to Micro-USB type The USB cable can be used to power, control, and configure the BT860.
Stand-off Screw nuts (4); Stand-off (4)
Pin header fly leads Leads for easy prototyping into host board (6)
Insert card Provides links to additional information including BT860 User Manual, Utilities, Schematics, and Quick Start Guides.
External antenna Only supplied with DVK-BT860-ST. Antenna supplied is Laird part # 0600-00040.
