Core module uses HC-06, leads from the module interface includes VCC, GND, TXD, RXD, reserve LED status output pin, the microcontroller can bejudged by the foot state Bluetooth has connected KEY pin slave invalid.
LED indicate Bluetooth connection status, flashing Bluetooth connectivity,lit the Bluetooth connection and open a port.
Backplane 3.3V LDO input voltage 3.6 ~ 6V, current is about 30mAunpaired, paired about 10mA, the input voltage to prohibit more than 7V!
The interface level 3.3V, can be directly connected the various SCM (51, AVR, PIC, ARM, MSP430, etc.), the 5V MCU also can be connected directly,without MAX232 can not go through the MAX232!
Open to the effective distance of 10 meters（More than 10 meters is also possible, but do not guarantee the quality of the connection to this distance.）.
