HC 08 Bluetooth 4.0BLE Serial Port Module

HC 08 Bluetooth 4.0BLE Serial Port Module

The HC-08 module operates using the Bluetooth Low Energy (BLE) standard, specifically designed for short-range wireless data exchange with minimal energy usage.
It works as a slave device, capable of pairing with BLE-enabled smartphones, tablets, and computers.
Unlike traditional Bluetooth modules that consume more power, the HC-08 is optimized for low-current operation, making it perfect for battery-powered and portable applications.

This module uses a simple UART interface for communication, making integration with microcontrollers straightforward. Developers can use AT commands to configure parameters such as the device name, baud rate, and password — giving flexibility and control over wireless communication behavior.
