V. Features
1 , the power supply voltage 3.3V, when unpaired current of about 30mA, paired about 10mA, the absolute prohibition of reverse power !
2, led pin indicates the status of the Bluetooth connection , the output pulse represents no Bluetooth connectivity, high output indicates that Bluetooth is connected and open ports
3 , interface level 3.3V, can be directly connected to various SCM (51, AVR, PIC, ARM, MSP430 , etc. ), 5V microcontroller can also be directly connected , can not pass without MAX232 MAX232!
4 , modules and computer access , followed MAX3232 chip connected to the computer's serial port
5 , open to the effective distance of about 10 meters , but the distance does not make this connection quality assurance
6 , after the pair when full-duplex serial interface , without having to know any Bluetooth protocol , but only supports 8 data bits, 1 stop bit , no parity communication format , which is the most commonly used communication format does not support other formats .
7 , when no Bluetooth connection support setting the baud rate , name , passkey via AT commands , power-down save parameter settings . After Bluetooth connection is automatically switched to transparent mode
8 , small size (2.7cm * 1.3cm), factory chip production to ensure the placement quality .
9 , the link from the machine, computer , Bluetooth with Bluetooth function from the host with a variety of functions , most Bluetooth phones , PDA, PSP and other intelligent terminal pairing , pairing between devices
