HC-06 Bluetooth Master Module

Product Description

HC-06 Bluetooth Master Module

The difference between the master and slave 
Paired only with the slave master, not with cell phones, computers and other pairing, can not be searched for two devices directly via Bluetooth serial communication, such as between the microcontroller and microcontroller serial cable with microchips, etc., using the method and serialthe same; 
Computer, Bluetooth host, most mobile phones with Bluetooth, PDA, PSP and other intelligent terminals with Bluetooth pairing with a variety of functions from, from between the machine can not be paired. 
Only one pairing between master and slave. 

Product Features: 
1, the core module HC-06 main modules, leads interface includes VCC, GND, TXD, RXD, KEY pin high pulse can be triggered to clear the pairing information search again 
2, led indicate Bluetooth connection status, flash unpaired, slow flash indicates paired but not connected with from, Steady has connected on follow 
3, bottom set LDO, the input voltage is 3.6 ~ 6V, with anti-reverse function, reverse module does not burn 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 directly connected 
5, open to the effective distance of 10 meters (power rating of CLASS 2), does not exceed the quality of the connection is made to ensure that this distance 
6, after the pair when using full-duplex serial port, support from 1200bps ~ 1382400bps between common baud rates (see the specific manual), without having to know any Bluetooth protocol, but only supports 8 data bits, 1 stop bit (parity can be set) communication format, which is the most common communication format, not support other formats. 
7, not only establish a Bluetooth connection (LED flashes) set the baud rate supported by AT commands, the pairing password, power-down save parameter settings. After Bluetooth connection is automatically switched to transparent mode does not respond to AT commands 
8, small size (3.57cm * 1.52cm), chip production plant to ensure the quality of the patch. And set transparent shrink tube, both dust and beautiful but also anti-static. 
9, the latest version number is currently bottom V1.06, adds support for TXD, RXD pin protection circuit, which greatly reduces the chance of damage to the pin 
10, the link to the host, paired only with the HC06 slave nor pairing between the host
