The BT800 series of USB HCI devices are designed to meet the needs of OEMs adding robust
Bluetooth connectivity and using embedded Bluetooth stacks within these products.
Leveraging the market-leading CSR8510 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.
With a tiny footprint as small as 8.5 x 13 mm, yet output power at 8 dBm, these modules are
ideal for applications where designers need high performance in minimal 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 an HCI interface and have native support for Windows and Linux Bluetooth software stacks.
All BT800 series devices are fully qualified as Bluetooth Controller Subsystem products. 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 excellent RF performance with integrated antenna and additional band
pass filters. It further reduces regulatory and testing requirements for OEMs and ensures a hassle free development
cycle. As an additional benefit of the BT800 series, Laird has implemented CSR's HID (Human Interface Device) Proxy
Mode enabling out of the box HID connectivity for pointing devices and / or keyboard functionality, requiring zero
host device software or configuration.
A fully featured, low-cost developer's kit is available for prototyping, debug, and integration testing of the BT800
series modules and further reduces risk and time in development cycles.
Note: Laird also offers a BT800-ST version which is a trace pin variant of the BT800 for use with an external
antenna.
