Keyestudio HC-06 Wireless Bluetooth Module for Arduino

The Keyestudio HC-06 Wireless Bluetooth Module is an easy-to-use serial communication tool designed to add wireless connectivity to your microcontroller projects. Operating on the globally recognised 2.4GHz ISM band, this module is ideal for students, educators, and hobbyists looking to establish reliable wireless data links between Arduino boards and external devices.

Simplified serial wireless communication

This module allows you to easily achieve serial wireless data transmission for your electronics projects. It features a straightforward serial interface that simplifies the overall design and shortens your development cycle.

Optimised power efficiency

Adopting the Bluetooth 2.1+EDR standard, the module utilises a 0.5-second signal transmit interval between devices. This substantially reduces the workload of the Bluetooth chip, allowing more sleeping time to conserve power.

Reliable high-frequency operation

Operating on the popular 2.4GHz ISM frequency band, the module uses Gauss Frequency Shift Keying modulation. It delivers a transmit power of 4dBm or less (second stage) with a receiver sensitivity of -84dBm or less at a 0.1% Bit Error Rate.

Versatile transmission speeds

The module supports asynchronous transmission speeds up to a maximum of 2.1Mbps (with 160kbps return), as well as synchronous speeds of 1Mbps/1Mbps. This ensures responsive data transfer for real-time monitoring and control.

Standard power and temperature limits

Designed for standard prototyping setups, the module runs on a 5V DC supply voltage at 50mA. It is built to operate reliably in environmental temperatures ranging from -20 to 55 degrees Celsius.

Secure serial port configuration

The module supports both major and minor Bluetooth serial port configurations. For safe wireless communication, it features built-in authentication and encryption security protocols.
