Product Features : 1 , the core module from the module using the HC-06 , leads interface includes VCC, GND, TXD, RXD, aside LED status output pin , the microcontroller can be connected via Bluetooth to determine whether the pin state , KEY pin of the slave invalid 2, led indicate Bluetooth connection status , flashes to indicate there is no Bluetooth connection , Steady Bluetooth port is connected and turned on 3 , bottom 3.3V LDO, the input voltage 3.6 ~ 6V, when unpaired current of about 30mA, the pairing of about 10mA, the input voltage must not exceed 7V! 4 , the interface level is 3.3V, you can directly connect a variety of SCM (51, AVR, PIC, ARM, MSP430 , etc. ), 5V microcontroller can also be connected directly , not through without MAX232 MAX232! 5 , open to 10 meters effective distance of over 10 meters are possible, but do not make this connection to ensure the quality of distance 6 , after the pair when using full-duplex serial port , without having to know any Bluetooth protocol, but only supports 8 data bits, 1 stop bit , no parity communication format , which is the most common communication format , not support other formats . 7 , establish a Bluetooth connection when not support setting the baud rate , the name , the pairing password via AT commands , parameter set -down to save . After Bluetooth connection is automatically switched to transparent mode 8 , small size (3.57cm * 1.52cm), chip production plant to ensure the quality of the patch . And set transparent shrink tube , dust and beautiful, and there is some anti-static capabilities. 9 , the link from the machine, from a performance with a variety of functions with Bluetooth Computer capacity, Bluetooth host , most Bluetooth phones , PDA, PSP and other intelligent terminal pairing between slaves can not be paired .
