HC-06 Bluetooth 2.0 Serial Wireless Module (Slave Only) for Arduino, ESP32, Raspberry Pi, and Microcontroller Projects

🛠️ HC-06 Bluetooth 2.0 Serial Wireless Module (Slave Only) for Arduino, ESP32, Raspberry Pi, and Microcontroller Projects

The HC-06 Bluetooth Module is a cost-effective and easy-to-use Bluetooth Serial Port Profile (SPP) module designed specifically to function as a slave device. It allows microcontrollers like Arduino, ESP32, STM32, and Raspberry Pi to communicate wirelessly via Bluetooth 2.0 using simple UART (serial) communication.

Unlike the HC-05, the HC-06 operates in slave mode only. This makes it ideal for applications where you need a reliable device that can pair with a smartphone, PC, or master Bluetooth device for basic wireless serial data communication.

The module is highly popular in DIY electronics, robotics, home automation, and embedded systems for providing wireless connectivity without complex setup.
