The BT800 series of Class 1 USB HCI modules and packaged USB Dongle are Laird's first dual-mode Bluetooth v4.0 offerings, bringing support for Classic Bluetooth and Bluetooth Low Energy (BLE) for operating system backed devices.

Leveraging the market-leading CSR 8510 A10 chipset, the BT800 series provides exceptionally low power consumption with outstanding range. Supporting the latest Bluetooth v4.0 Specification with EDR (Enhanced Data Rate), the Laird BT800 series enables OEMs to accelerate their development time for leveraging either Classic Bluetooth or Bluetooth Low Energy (BLE) into their operating system based devices.

The BT800 has a tiny footprint as small as 8.5 x 13mm, still offering output power at 8dBm, making these modules ideal for applications where designers need both performance and minimum size. For maximum flexibility in systems integration, the modules are designed to support a full speed USB interface plus GPIO and additionally I2S and PCM audio interfaces.

These modules present a Bluetooth standard HCI interface and have native support for Windows and Linux Bluetooth software stacks.  All BT800 series devices are fully qualified as a Bluetooth Subsystem. This also allows designers to integrate their existing pre-approved Bluetooth Host and Profile subsystem stacks to gain a Bluetooth END product approval for their products.

The BT800 series is engineered to provide for excellent RF performance with an integrated antenna and additional band pass filters to further reduce the regulatory and testing requirements for OEMs and ensures a hassle free development cycle.. As an additional benefit of the BT8000 series, Laird has implemented CSR's HID (Human Interface Device) Proxy Mode enabling out of the box HID connectivity for BLE pointing devices and / or BLE keyboard functionality, requiring zero host device software or configuration.

The BT820 is a packaged USB Dongle version of the BT800 module, that allows OEMs to plug the device into any Windows or Linux device that supports USB connectors and has an  inbuilt Bluetooth software stack in its operating system.

A fully featured, low-cost developer's kit (DVK-BT800) is available for prototyping, debug and integration testing of the BT800 series modules and further reduces risk and time in development cycles.
