needs of developers who wish to add robust, short range Bluetooth data connectivity to their products. They

are based on the market leading Cambridge Silicon Radio BC04 chipset, providing exceptionally low power

consumption with outstanding range.

With physical sizes as small as 12.5 x 18.0mm and best of class, low-power operation, these modules are the

ideal choice for applications where designers need both performance and minimum size. For maximum

flexibility in systems integration, the modules are designed to support a separate power supply for I/O.

To aid product development and integration, Laird Technologies has integrated a complete Bluetooth

protocol stack within the modules, including support for the Bluetooth Serial Port Profile. The modules are

fully qualified as Bluetooth End Products, allowing designers to integrate them within their own products with

no further Bluetooth Qualification. They can then list and promote their products on the Bluetooth website

free of charge.

A comprehensive AT command interface is included, which simplifies firmware integration. Combined with a

low cost developer’s kit, this ensures that the choice of Laird Technologies Bluetooth modules guarantees the

fastest route to market.
