HC-05 Bluetooth Transceiver Host Slave/Master Module Wireless Serial+6pin Dupond Arduino Projects Robots
1.the core module using HC-05 from the module, leads to interface to VCC, GND, TXD, RXD, the KEY pin and LED status leads to the foot (STATE)
LED indication Bluetooth connection status, flash that there is no Bluetooth connection, slow flash into the AT mode, dual-flash Bluetooth is connected and open port
2. Base plate set anti-reverse diode with 3.3V LDOs, input voltage :3.6 ~ 6V, unpaired:about 30mA, paired: 10mA more than 7V is not allowed
3. the interface power level 3.3V, can be directly connected a variety of microcontroller (51 AVR, the PIC, ARM, the MSP430) and 5V MCU
5. after pairing when full-duplex serial without having to know any of the Bluetooth protocol to support 8 data bits, 1 stop bit, you can set the parity communication format, which is the most common communication format does not support other formats.
6. can set the parameters and query information via the AT command mode by pulling up 34 feet
7.small size (3.57cm * 1.52), factory chip production, to ensure that the patch quality. And sets of transparent heat-shrinkable tube, dust appearance, and there is some anti-static capability.
8.can switch host and slave mode by changing AT command, the specified equipment can be connected through the AT command
9, support standard baud rate from 4800bps ~ 1382400bps
