Bluetooth Module

The Arduino Bluetooth Module HC-06 is a reliable and cost-effective solution for adding wireless communication to your microcontroller projects. Based on the CSR BC04 Bluetooth 2.0 chipset, this module operates exclusively in slave mode, making it ideal for receiving data from master devices such as smartphones, tablets, or PCs.

It features a built-in 2.4GHz PCB antenna and supports a communication range of up to 10 meters in open environments. The module uses a simple UART interface (VCC, GND, TXD, RXD) with a default baud rate of 9600 bps, allowing seamless integration with Arduino and other microcontrollers. With onboard voltage regulation, it accepts input voltages from 3.3V to 6V.
