Wireless Serial Bluetooth Transceiver Master-Slave Module
This is a type of low energy data transmission Bluetooth module. Combining the advantages of compact size£¬ extra low power consumption£¬ strong anti-interference and long communication distance£¬ it is very suitable for short range wireless communication in Things of Internet. The module integrates PCB antenna on board. It can be used to communicate with other Bluetooth devices such as Android system. Through AT commands£¬ the user can modify the baud rate£¬ master-slave role£¬ device name£¬ pass word and other parameters. At the end of the AT command line should be the carriage and return characters. AT commands can take effect only when the module is not connected with other device.The module enters data transparent mode once it is connected. Features: - Bluetooth protocol: Bluetooth Specification V2.1+EDR. - Operating Frequency: 2.4GHz ISM band. - Transfer rate: 6Kbps. - Power consumption: Standby current is 400uA~1.5mA£¬ transmission current 20mA (MAX). - Function: Master and slave in one.You can modify the role by AT command. - Operating voltage: 3.2~5.5V (On-board 3.3V LDO Regulator). - Interface logic voltage: 3.3V / 5V compatible(On-board level shift circuit). - Logic Interface Type: UART TTL serial port. - Serial port baud rate: 9600 (default)£¬ can be modified to other values ?by AT command. - UART communication format: 8N1 (default). - Applications: Bluetooth control smart car£¬ Bluetooth wireless data transmission£¬ wireless keyboard and mouse£¬ smart home.
