Module HC-06 Bluetooth

Description

The HC-06 is a popular Bluetooth module often used for wireless communication in electronics projects and applications. It is part of the HC series of Bluetooth modules and is widely used for enabling Bluetooth connectivity in various devices. Here are the key features and details of the HC-06 Bluetooth module:

1. **Bluetooth Version:** The HC-06 module is based on Bluetooth version 2.0, which supports the Serial Port Profile (SPP). It allows for simple and transparent serial communication between devices.

2. **Serial Communication:** The HC-06 module is designed to provide a serial UART (Universal Asynchronous Receiver-Transmitter) interface for communication. It’s commonly used to establish wireless connections with microcontrollers like Arduino and other embedded systems.

3. **Operating Mode:** The module operates in a transparent mode, which means it simply transfers data between the connected devices. It doesn’t require complex command sequences for data transfer.

4. **Slave Role:** The HC-06 module typically operates in the slave role, which means it listens for incoming Bluetooth connections from master devices, such as smartphones, tablets, or other Bluetooth-enabled devices.

5. **Baud Rate:** You can configure the module to operate at a specific baud rate to match the communication speed of your microcontroller or device. Common baud rates include 9600, 57600, and 115200 bps.

6. **Voltage Compatibility:** HC-06 modules are available in 3.3V and 5V versions. It’s important to select the version that matches the voltage levels of your microcontroller or device.

7. **Pairing:** For some applications, you might need to pair the HC-06 module with a master device, which involves entering a passcode. Once paired, the master device can establish a wireless serial connection with the module.

8. **AT Commands:** The module supports a set of AT commands that can be used to configure various settings, including the device name, pairing code, and baud rate. These settings can be changed to suit your specific project requirements.

9. **Applications:** The HC-06 Bluetooth module is used in a wide range of applications, including wireless data transmission, remote control, home automation, and robotics.

10. **Range:** The effective range of the HC-06 module is typically around 10 meters (approximately 30 feet), but it can vary depending on environmental factors and interference.

11. **Power Supply:** The module requires a stable power supply voltage within its specified operating range (3.3V or 5V), and it should be connected to the appropriate voltage source.

The HC-06 Bluetooth module is a cost-effective solution for adding wireless communication capabilities to your projects. It is often used for remote control and data exchange between devices, making it a popular choice for hobbyists, makers, and developers in the field of IoT (Internet of Things).
