HC-06 Bluetooth Module for Arduino, ESP32 & Raspberry Pi
The HC-06 Bluetooth Module is a compact and reliable wireless serial communication module designed for embedded systems, robotics, IoT, and automation projects. Utilizing Bluetooth 2.0 + EDR technology, it allows microcontrollers to communicate wirelessly with Bluetooth-enabled devices such as Android smartphones, tablets, laptops, and computers.
Unlike the HC-05, the HC-06 is designed to operate in Slave mode only, making it an excellent choice for projects where a microcontroller needs to receive commands or transmit data to a paired Bluetooth device. Communication is achieved through a standard UART (TTL Serial) interface, allowing quick integration with Arduino, ESP32, Raspberry Pi, NodeMCU, STM32, PIC, AVR, and other development platforms.
Whether you're creating a Bluetooth-controlled robot, wireless sensor system, smart home project, or educational prototype, the HC-06 Bluetooth Module provides dependable wireless connectivity with minimal setup.
