BT700 Series Bluetooth Modules


Class 1 Bluetooth modules from Laird Technologies

Every BT700 series Bluetooth® module from Laird Technologies is designed to add robust, long-range Bluetooth data connectivity to any device. Based on the market-leading Cambridge Silicon Radio (CSR) BC04 chipset, BT700 modules provide exceptionally-low power consumption with outstanding Class 1 range via 18 dBm of transmit power. The BT730 module supports Bluetooth Version 2.0, and the BT740 module supports Bluetooth Version 2.1 specification. Both modules include Secure Simple Pairing (SSP), which improves security and enhances the ease-of-use for end customers. A broad range of Bluetooth profiles such as Serial Port Profile (SPP) and other vital features make BT700 modules superior to other Class 1 Bluetooth modules.

With a compact footprint of 15.29 x 28.71 mm, the modules deliver maximum range with a minimum size. Another integration advantage is the inclusion of a complete Bluetooth protocol stack with support for Multi-Point connections and numerous Bluetooth profiles, including Serial Port Profile (SPP), Human Interface Device profile (HID), and Health Device Profile (HDP). BT700 series modules are fully qualified as Bluetooth End Products, enabling designers to integrate the modules in devices without the need for further Bluetooth qualification. In addition, each module carries FCC Modular, IC, and complete CE certification to further reduce the regulatory approval process for OEM integrators.
