SHAHIDEER HC-05 Bluetooth Serial Pass through Module Wireless Serial Communication Board HC05 for Arduino

Description

SHAHIDEER HC-05 Bluetooth Serial Pass-through Module Wireless Serial Communication Board HC05 for Arduino 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, can be switched via AT commands as master or slave mode , the device can be connected via AT commands specified 9, support from the Inter- standard baud rate 4800bps ~ 1382400bps Package Contents : 1 x HC-05 Bluetooth Serial Pass through Module
