HC05 Bluetooth Module

The HC05 Bluetooth Module is a user-friendly Bluetooth SPP (Serial Port Protocol) module, specifically engineered for wireless serial communication tasks. It features accessible pins on the board, facilitating easy integration with Arduino and other similar projects for swift prototyping. The HC05 stands out from many Bluetooth modules due to its support for master mode, which enhances its versatility in communication roles.Operating on Bluetooth 2.0, this module offers a communication range of up to 10 meters in open spaces and operates at a frequency of 2.4 GHz. It is suitable for a broad spectrum of projects, ranging from hobby and robotics to academic research. The HC05 module has the capability to function as both a master and a slave, a feature not available in the HC06, which is strictly a slave-only module.
