Description: HC 05 Bluetooth Module Serial Port HC-05 Integrated Bluetooth Module
HC05 HC-05 6Pin Bluetooth Module Serial Port Integrated Bluetooth Module Wireless Serial Port 6 Pin HC05 Board For Arduino Electrical Circuitry & Parts
you need to attach this to a computer. You can either solder a 6-pin header or individual wires. Unit comes without a connector. Please see related male and female pins below. And now, we provide HC-05, HC-05 could be setting to Master or Slave by user. HC-05 just be Master or Slave, that could be customized.
It is HC-05.
Use the CSR mainstream bluetooth chip, bluetooth V2.0 protocol standards.
Module working voltage 3.3 V.
Potter default rate of 9600, the user can be set up.
The core module size : 28 mm x 15 mm x 2.35 mm.
Working current: matching for 30 MA, matching the communication for 8 MA.
Dormancy current: no dormancy.
Used for GPS navigation system, water and electricity gas meter reading system.
With computer and bluetooth bluetooth adapter, PDA, seamless connection equipment
1.PCB Size: 37.3mm (Long) *15.5mm (wide)
2. Weight: 3.5g
3. Input voltage: 3.6V–6V, prohibit exceeding 7V
4. Leads 6 feet: EN/VCC/GND/RXD/TXD/STATE (Bluetooth state leads, not connected output low level, the output high level after connection)
5. With the connection status indicator, LED flash indicates no Bluetooth connection; Led slow flash indicates enter at command mode
6. On-board 3.3V voltage regulator chip, input voltage DC 3.6V-6V; When not paired, current about 30mA (due to LED lights flashing, current in the state of change); After the pairing succeeds, the current is about 10mA
7. Effective transmission distance of 10 meters in open area, more than 10 meters is possible, but not to ensure the quality of the connection
8. After pairing succeeds, can be used as full duplex serial port. No need to understand any Bluetooth protocol, but only support 8-bit data bits, 1-bit stop bits, no parity communication format. This is also the most commonly used communication format, does not support other formats!
9. Press the key and then power up the Bluetooth module to enter at mode, set parameters and query information
10. Can switch host and machine mode from at command
11. The module default baud rate is 9600, the default pairing password is 1234, the default name is HC-05
VCC: Connect the power supply positive
GND: Connecting the cathode
RXD: The receiver, the Bluetooth module receives data from other devices, and the sending end TXD of the other devices normally
TXD: Send end, Bluetooth module sends data to other equipment; the receiving end RXD of the other equipments normally
En: To enable the end, need to enter the at mode when 3.3V
State: It tells whether module is connected or not. It acts as a status indicator.
Wireless communication between two microcontrollers
Communicate with Laptop, Desktops and mobile phones
