HC05 Description

Short technical summary and product information.

The HC-05 is a widely used Bluetooth module designed to integrate full-duplex wireless communication into various electronic projects. It operates with a supply voltage typically around +5V, ranging from 4V to 6V, and consumes approximately 30mA of current.

 

This module supports serial communication via USART and is TTL compatible, making it easy to interface with microcontrollers like Arduino. It follows the IEEE 802.15.1 standard and utilizes Frequency-Hopping Spread Spectrum (FHSS) technology for reliable wireless data transfer. The HC-05 can function in Master, Slave, or Master/Slave modes, offering flexibility in network configuration.

 

Key default settings include a Bluetooth name of "HC-05", a password of "1234" or "0000", and a default communication mode of Slave. The module supports multiple baud rates for both Data Mode (9600 bps) and Command Mode (38400 bps), with a wider range of supported rates available for configuration.

 

It is suitable for applications requiring data transfer between microcontrollers, or between a microcontroller and devices like laptops or mobile phones. However, it is not intended for high-bandwidth multimedia streaming.
