They are based on the market leading Cambridge Silicon Radio BC04 chipset, providing exceptionally low power consumption with outstanding range. They support the latest Bluetooth Version 2.1 Specification with EDR (Enhanced Data Rate). As well as increasing data throughput up to 2.1 Mbps, this provides the important advantage of Secure Simple Pairing, which improves security and enhances the ease of use for end customers. With physical sizes as small as 12.5mm x 18.0mm and best of class, low power performance, 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 separate power supplies for I/O and the USB interface. These modules present an HCI interface through a USB interface and are fully qualified as Bluetooth Controller Subsystem Products. This allows designers to integrate them existing pre-approved Bluetooth Host and Profile subsystem stacks to gain a Bluetooth END product approval for their product. A low cost developer’s kit is available for prototyping. This ensures that the choice of Laird Technologies Bluetooth modules guarantees the fastest route to market. 1.1 Features and Benefits Bluetooth v2.1+EDR Adaptive Frequency Hopping to cope with interference from other wireless devices Support for Secure Simple Pairing External or internal antenna options HCI Interface over USB Bluetooth controller subsystem product qualified Compact size Class 2 output – 4dBm Low power operation USB interface Multipoint Support PCM & SCO for external codec Wi-Fi coexistence hardware support 1.2 Application Areas Embedded devices Phone accessories Security devices Medical and wellness devices Automotive applications Bluetooth® advertising ePOS |
