Description

The HC-06 Bluetooth module allows us to connect our projects with Arduino to a smartphone, cell phone or PC wirelessly (Bluetooth), with the ease of operation of a serial port. The transmission is carried out totally transparently to the programmer, so it is connected directly to the serial pins of our preferred microcontroller (respecting the voltage levels, since the module is powered by 3.3V).

All module parameters can be configured by AT commands. The board also includes a 3.3V regulator, which allows the module to be powered with a voltage between 3.6V - 6V. This module is the ideal complement for our robotics, home automation and remote control projects with Arduino, PIC, Raspberry Pi, ESP8266, ESP32, STM32, etc.

Main features:

DC operating voltage: 3.6V ~ 6V
Operating current: < 40 mA
Current Mode Sleep: < 1mA
Range: 10 meters
Communication speed: 1200 bps at 1.3 Mbps
Adjustable baud rate: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 (default 9600)
It has an RX PIN and a TX which makes the serial communication through the reception and output of logical levels of 3.3 V.
This module comes with installed firmware: with default serial configuration 9600/N/1 and pairing code: 1234.
It has a red status LED that flashes when it is turned on and is visible, it remains fixed when the pairing and the serial connection is open.
