The BTM430 and BTM431 Bluetooth® modules from Laird Technologies have

been designed to meet the 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 a footprint as small as 12.5 mm x 18.0 mm for the BTM430 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 or Multipoint Packet Protocol is included, which

simplifies firmware integration. This ensures that the choice of Laird Technologies

Bluetooth modules guarantees the fastest route to market.
