Input voltage: 3.6V-6V, prohibit exceeding 7V
Leads 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 mode
On-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 10mA
Interface level 3.3V, you can directly connect a variety of microcontroller (51 / AVR / PIC / ARM / MSP430 etc.), 5V microcontroller can also be directly connected
Directly connected to the microcontroller serial port, not through the MAX232 chip
Open area effective transmission distance of 10 meters
After 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 format
You can switch between Receiver and Transmitter mode via AT commands
