LAIRD TECHNOLOGIES BT740-SC 模块, BTV2.1增强1级, 外部天线
The module is designed to add robust, long-range Bluetooth data connectivity to any device. Based on the market-leading Cambridge Silicon Radio CSR BC04 chipset, the module provide exceptionally low power consumption with outstanding Class 1 range via 18 dBm of transmit power. A broad range of Bluetooth profiles such as Serial Port Profile SPP and other vital features make the modules superior to other Bluetooth modules. 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. 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.
