is a Bluetooth AT Data Module with integrated antenna. 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 small footprint 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, it has integrated a complete Bluetooth protocol stack within the modules, including support for the Bluetooth Serial Port Profile. A comprehensive AT command or Multipoint Packet Protocol is included, which simplifies firmware integration. This ensures that the choice of this Bluetooth modules guarantees the fastest route to market.
