HC-06 4pin Bluetooth Module (Slave) Without Button

The HC-06 Bluetooth Module is one of the most popular and reliable Bluetooth solutions for adding simple wireless serial communication to embedded projects. Designed to operate exclusively in slave mode, the HC-06 makes it extremely easy to establish wireless UART communication between microcontrollers and Bluetooth-enabled devices. Whether you’re using Arduino, ESP32, Raspberry Pi, STM32, PIC, or any other development board, the HC-06 provides a convenient and beginner-friendly way to send and receive data wirelessly. Built around the CSR BC4 chipset, the HC-06 supports Bluetooth V2.0 EDR, ensuring stable and fast communication for various DIY and industrial applications. The module includes a built-in 3.3V voltage regulator, allowing you to power it safely from 3.6V to 6V inputs. Essential pins—VCC, GND, TXD, RXD—are broken out for easy integration with breadboards and microcontroller projects. Once paired with a Bluetooth master device such as a PC, laptop, Android phone, PSP, or PDA, the HC-06 functions like a standard UART interface. This means that after pairing, you can simply read and write data as if using a normal serial port—no complicated drivers or protocols required. With a wide range of supported baud rates and accessible AT commands, users can easily configure the Bluetooth name, pairing password, and baud rate when the module is not connected. Because of its reliability, affordability, and ease of use, the HC-06 Bluetooth Serial Module is ideal for wireless robot control, data logging, home automation, sensor monitoring, educational electronics, and many IoT prototypes. Its simplicity and strong compatibility make it a top choice for electronics hobbyists, students, and professionals.
