Input voltage: 3.6V -6V, prohibit
exceeding 7VLeads 6 feet: EN / VCC / GND / RXD / TXD / STATE (Bluetooth state leads, not connected output low level, the output high level after connection)With the connection status indicator, LED flash indicates no Bluetooth connection; Led slow flash indicates enter at command modeOn-board 3.3V voltage regulator chip, the input voltage DC 3.6V -6V; When not paired, current about 30mA (because LED lights flashing, current in the state of change); After the pairing succeeds, the current is about 10mAInterface level 3.3V, you can directly connect a variety of microcontroller (51 / AVR / PIC / ARM / MSP430 etc. ), 5V microcontroller can also be directly connectedDirectly connected to the microcontroller serial port, not through the MAX232 chipOpen area effective transmission distance of 10 metersAfter the pairing is successful, can be used as a full-duplex serial interfaces. Without knowing any of the Bluetooth protocol, but only supports 8 data bits, 1 stop bit, no parity communication formatYou can switch between Receiver and Transmitter mode via AT commandsModules default baud rate is 9600, the default passkey is 1234, the default name for the
HC-05Wiring method:
VCC: Connect
