Product Description

HC-05 Wireless Serial Bluetooth Module Parameters:
1.PCB Dimensions: 37.3*15.5mm
2.Weight: 3.5g
3.Input voltage: 3.6V - 6V, 7V ban over
4.Power anti-reverse, reverse module does not work
5.Leads to six feet: EN / VCC / GND / RXD / TXD / STATE (Bluetooth status leads to the foot, is not connected to the output low, after connecting the output high)
6.With the connection status indicator, LED flash means no Bluetooth connectivity; LED flashes slowly that enter the AT command mode
7.On-board 3.3V regulator chip, the input voltage DC 3.6V-6V; when unpaired, current of about 30mA (because LED lights flashing, the current state of change); after the pairing is successful, the current is about 10mA
8. Interface level 3.3V, can be directly connected to various microcontroller (Arduino / 51 / AVR / PIC / ARM / MSP430 etc.), 5V microcontroller can also be directly connected. Directly connected to the microcontroller serial port, you can not go through MAX232 chip!
9.Open area effective transmission distance of 10 meters, over 10 meters are possible, but do not guarantee the quality of the connection
10.After the pairing is successful, can be used as a full-duplex serial interfaces. Do not need to know anything about the Bluetooth protocol, but only supports 8 data bits, 1 stop bit, no parity communication format. This is the most commonly used communication format, other formats are not supported!
11.Press the key to give access to the Bluetooth module is powered AT mode, set the parameters and query information
12. You can switch between master and slave mode via AT commands
13. The module defaults to 9600, the default passkey is 1234, the default name for the HC-05
14. shrinkable tube with transparent protection
HC-05 Wireless Serial Bluetooth Module Wiring Methods:
VCC: positive power supply
GND: power supply is negative
RXD: the receiving end, a Bluetooth module receives from other devices to the data; normally connect the sender to other devices TXD
TXD: sending end, the Bluetooth module to send data to other devices; normally connected to other devices receiving terminal RXD
EN: enabled client, you need to enter the AT mode pick 3.3V
