A set of HC-05 Bluetooth serial adapter modules for CSR 51 microcontrollers

Product Description

A set of HC-05 Bluetooth serial adapter modules for CSR 51 microcontrollers

HC-05Master-slave integrated Bluetooth serial port module Master-slave available commands, rich range of commands(Power supply voltage 3.3V ~ 3.6V)

HC-06The main control and the main control switch are self-integrated with the Bluetooth serial port module and have their own instructions, which are simpler and easier to use than HC-05.(Power supply voltage 3.3V ~ 3.6V)

host:It is used for this device to search, other devices cannot search. (with white dot bluetooth module)

slave:The device is used for searching, and cannot actively search for other devices.

After the master-slave is connected, it is equivalent to using a serial cable. At this time, there is no distinction between the master and the slave, that is, the transparent mode.

[This module can be set as master or slave, master and slave pair can communicate between slave and slave or host

Can not communicate with each other, from the bluetooth function and communication pairing with computers, mobile phones, etc., the default is to buy a slave]

[notes: HC-05 and 06 of the host can be paired with each other]

1. Adopt mainstream CSR Bluetooth chip, Bluetooth V2.0 protocol standard.

2. Module power supply voltage: 3.3V ~ 3.6V.

3. Default parameters: baud rate 9600, pairing code 1234, slave mode.

4. The size of the core module is: 27mm x 13 mm x 2mm.

5. Working current:pair:30~40mAPairing communication not completed:2~8Macommunicate:8mA without sleep.

6. Communication distance: 10M under open conditions, about 8M under normal use environment.

7. Used in GPS navigation system, utility meter reading system, industrial and mining site industrial control system,Seamless connection with bluetooth laptops, computers with bluetooth adapters, PDAs and other devices.

8. It can wirelessly upgrade the STC microcontroller and download the program.
