HC-05 RF Wireless Bluetooth Transceiver Module RS232 / TTL to UART Converter and Adapter
- Description
HC-05 Bluetooth Module can be used in a Master or Slave configuration, making it a great solution for wireless communication. You can use it simply for a serial port replacement to establish a connection between MCU and GPS, PC to your embedded project, etc.
Core module HC-05 leads from the module interface including VCC, GND, TXD, RXD, KEY pin and LED Status pin-out (STATE)
Led indicate Bluetooth connection status, flash Bluetooth connectivity slow flash into AT mode, double flash Bluetooth connection and open a port
Backplane set anti-reverse diode with 3.3V LDO input voltage of 3.6 ~~ 6V unpaired current is about 30mA paired approximately 10mA input voltage to prohibit more than 7V!
The interface level 3.3V direct connection the various SCM (51, AVR, PIC, ARM, MSP430, etc.), the 5V MCU also can be directly connected, without MAX232 can not go through the MAX232!
Open to an effective distance of 10 meters, more than 10 meters is also possible, but not this distance connection quality assurance
When paired with a full-duplex serial port to use, do not need to know anything about the Bluetooth protocol support 8 data bits, 1 stop bit, parity can be set communication format, which is the most commonly used communication format does not support other formats.
Can be pulled up 34 feet into the AT command mode to set parameters and query information, compact (3.57cm x 1.52 cm), chip production factory guarantee placement quality. And sets of transparent heat shrink tubing, dust and beautiful, and anti-static.
Available through AT commands switch to host or slave mode via AT commands access the specified device supporting standard baud rate from 4800bps ~ 1382400bps
