1, the core module from the module using the HC-05 , leads interface includes VCC, GND, TXD, RXD, KEY pin , pin-out Bluetooth connection status (STATE), not connected to the output low , after connecting the output high
2, led indicate Bluetooth connection status , Bluetooth connection means no flash , slow flash indicates enter AT mode , double flash indicates Bluetooth is connected and open ports
3, bottom set anti-reverse diode with 3.3V LDO, the input voltage is 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 ( power rating of CLASS 2), more than 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 support 8 data bits, 1 stop bit, parity can be set communication format , which is the most common communication format , not support other formats.
7, can be pulled 34 feet into the AT command mode to set parameters and query information
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, can be switched via AT commands as master or slave mode , the device can be connected via AT commands
specified
10, support from the Inter- standard baud rate 4800bps ~ 1382400bps
