HC 06 4pin Bluetooth Module Slave Without Reset Switch
The HC-06 is a compact and reliable Bluetooth 2.0 serial communication module designed for wireless data transfer between microcontrollers and Bluetooth-enabled devices. This version features a 4-pin interface (VCC, GND, TXD, RXD) and operates exclusively in Slave mode, meaning it can connect to a master device such as a smartphone, computer, or another microcontroller with Bluetooth capability.
Known for its simplicity and stability, the HC-06 module is ideal for wireless serial communication, Arduino projects, and embedded system applications.
