HC-05 Bluetooth TTL Module
HC-05 Bluetooth TTL module supporting Master/Slave modes—ideal for Arduino, robotics, and wireless serial communication projects.
Description
The HC-05 Bluetooth TTL Module is a popular wireless communication module designed to provide Bluetooth serial connectivity between microcontrollers and Bluetooth-enabled devices. Supporting Bluetooth 2.0 + EDR and the Serial Port Profile (SPP), it enables reliable wireless data transmission for embedded applications.
The HC-05 module operates in both Master and Slave modes, allowing flexible configuration for various communication scenarios. It uses TTL-level UART communication, making it easy to interface with Arduino, ESP32, STM32, Raspberry Pi, and other microcontroller platforms.
Commonly used in wireless control, robotics, home automation, data logging, and mobile app-based projects, the HC-05 Bluetooth module offers stable performance, easy setup using AT commands, and low power consumption.
