Based on the market-leading Cambridge Silicon Radio (CSR) BC04 chipset, BT740 modules provide exceptionally low power consumption with outstanding Class 1 range via 18 dBm of transmit power. The modules support the latest Bluetooth Version 2.1 specification, including Secure Simple Pairing, 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 BT740 modules superior to other 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). BT740 modules are fully qualified as a Bluetooth End Products, enabling designers to integrate the modules in devices without the need for further Bluetooth Qualification. An integrated AT command processor interfaces to the host system over a serial port using an extensive range of AT commands. The AT command set abstracts the Bluetooth protocol from the host application, saving many months of programming and integration time. It provides extremely short integration times for data oriented Bluetooth applications. Included firmware provides programming support for multi-point applications that use up to seven simultaneous data connections to and from the robust BT740 module. A low-cost developer’s kit makes it easy for an OEM to integrate the module and guarantees the fastest route to prototype and then mass production. ## **Features & Benefits** - Bluetooth v2.1 - External or Internal Antennas - Comprehensive AT command set - Bluetooth EPL - Compact Footprint - Class 1 output - 18dBm - UART interfaces with GPIO & ADC ## **Application Areas** - Medical devices - ePOS terminals - Automotive Diagnostic Equipment - Barcode Scanners - Industrial Cable Replacement - Industrial Temperature range - Multipoint Capabilities with up to 7 simultaneous connections USA: +1.800.492.2320 Europe: +44.1628.858.940 Asia: +852.2923.0610 Full detailed product documentation is available at:- http://www.lairdtech.com/Products/Embedded-Wireless-Solutions/BluetoothRadio-Modules/BT700-Series/BT740/ wirelessinfo@lairdtech.com www.lairdtech.com/wireless The details contained within the document are subject to change.
