The HC-06 is slave module, interface VCC,GND,TXD,RXD,STATE,EN. State interface can tell the status of LED, EN is enable pin, the current consumption<20uA when it is closed

LED indicate the status of bluetooth connection: if the LED is flashing, it means the bluetooth does not connect, if the LED is light, it means the bluetooth connected

Anti-reverse diode, with 3.3V LDO

Input voltage: 3.6-6V,

Current: The current is 30mA when it is unparied, it is 10mA when it is paried. The input voltage can not over 7V

Interface level 3.3V, it can be connected with various SCM directly, such as: 51, AVR, PIC, ARM, MSP430, etc. It is not allowed to connected with MAX232

Effective Distance: 10 meters in the open field

After paried, it can be used as full-duplex serial, it do not need anything about bluetooth protocol, but only support 8 data bits, 1 stop bit and no parity communication format

When it without bluetooth connection, it support baud rate, name, passkey through AT command. The information will be saved when power is off. After connection, it will be changed to pass-through mode automatically

Product Size: 4.03cm*1.52cm

Compatible with computer, cell phone, PDA, PSP (which with bluetooth function)

The default password is 1234
