Module parameters:
1.PCB Size: 37.3mm (Long) X 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
Pinout Definition:
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
