1.This bluetooth modules use HC - 06 core chip , The interfaces include VCC, GND, TXD, RXD, reserved LED state output pin, MCU can state whether the bluetooth is connected or not, KEY pin is invalid to slave
2.Led indicates a bluetooth connection state, twinkle means no connection, LED light on means bluetooth connected and the port opened
3.Base board voltage is 3.3 V LDO, power imput is 3.3 ~ 6 V, unpaired current is about 30 ma, matched current is about 10 ma, the input voltage can't be higher than 7 V .
4.Interface level 3.3 V, can connect directly to a variety of MCU (51, AVR, PIC, ARM, MSP430, etc.), 5 V microcontroller can also be connected directly without MAX232 couldn't through MAX232.
5.effective distance of 10 meters or more than 10m in open space
6.The module can be used as full duplex serial port and no need to know any bluetooth protocol, It just support eight data bits, 1 stop bits, no parity checking of the communication format
7.Support when the bluetooth connection has not been established by pairing the AT command can set baud rate, name, password, set the parameters of the power save even bluetooth is not connected..bluetooth can automatically switch to transparent mode after connection
8.Small size (3.57 cm * 1.52 cm), with antistatic ability.
9.This module is slave, it can connect with kinds of computer with bluetooth function, bluetooth host, bluetooth mobile phone, PDA, PSP and some other intelligent terminal, the slaves can't match each other.(very important)
