HC05 Bluetooth Module

The HC05 Bluetooth Module is an easy-to-use Bluetooth SPP (Serial Port Protocol) module designed for wireless serial communication applications. With pins accessible on the board, it can be easily used on a breadboard with Arduino and other projects, enabling rapid prototyping. Unlike many Bluetooth modules, the HC05 supports master mode, offering greater versatility in communication roles.

This module supports Bluetooth 2.0, providing a communication range of up to 10 meters in open spaces and operates on a 2.4 GHz frequency. It can be used in a variety of projects, from hobby and robotics to academic research. The HC05 module can function as both master and slave, unlike the HC06, which is slave-only.
