HC-05 Master-Slave Bluetooth Module - AVR ARM Arduino
Universal Bluetooth master / slave module HC-05 HC05 - for Arduino, APM, AlexMos and MultiWii
The Bluetooth master / slave module allows you to connect any device with a phone, smartphone, tablet or other device wirelessly.
Standardized Bluetooth technology eliminates the problem of drivers and compatibility. The modules allow for communication up to 10m.
I work as a master or slave.
Connection through the UART port (pins RX, TX), serial - with a signal voltage of 3.3 V.
Watch out for the voltage of the UART signals (pins RX, TX) (cannot be 5V) (for Arduino only with a voltage divider or voltage converter).
The module has soldered Goldpin header connectors that allow you to connect the module to the breadboard or connect using DuPont wires.
The WAKEUP pins (switches the system into the AT command mode) and STATE (connected to the PIO1 status pin - pin 24) are led out in the form of holes, by default they do not have soldered connectors.
Transparent data transmission function - can be used with other devices with the Bluetooth v2.0 + EDR protocol.
Communication: UART (RX, TX)
-Verification mode: none
DATA Bits: 8 bits
Stop Bits: 1 bit
Supply voltage: 3.6 V to 6 V connected to the VCC pin.
UART communication pins (RX / TX) work with a voltage of 3.3 V.
Current consumption: approx. 80 mA (pairing)
Transmission current: 8mA (working)
Class 2 - transmitter power max. + 4 dBm
Range: up to 10 m
Password for pairing: 1234
Dimensions: 38 x 16 mm
Starting the module
In order to start the module, connect the supply voltage to the pin marked VCC.
The module will be detected by the computer as unknown system or HC-05.
To pair both devices, enter the password: 1234.
A virtual COM port will appear in the system, through which data can be sent using any terminal.
You can connect to the module:
Arduino boards - watch out for the voltage of the UART signals (cannot be 5V) (you cannot directly connect the Arduino Uno or Leonardo)
Compatible with Arduino UNO and MEGA 2560.
AlexMos Gimbal Controllers

Green: power indicator
flashing means no connection
a steady light indicates a connection has been established
