HC 06 Wireless Bluetooth Module without Baseplate
The HC-06 module provides wireless serial communication (UART) between microcontrollers and Bluetooth-enabled devices. It acts as a bridge to replace traditional wired serial connections, eliminating bulky cables and improving system flexibility.
The onboard CSR BC417143 chipset ensures stable performance, fast pairing, and reliable data transmission over distances up to 10 meters in open space. The module’s built-in PCB antenna offers good signal strength and range while maintaining a slim, lightweight form factor.
Designed for plug-and-play use, the HC-06 works seamlessly with popular microcontroller platforms like Arduino, ESP8266, ESP32, STM32, AVR, and Raspberry Pi. It uses TTL-level serial communication, so you can directly connect the TX and RX pins to your MCU (with voltage level adjustment for 5V systems).
The AT command interface allows easy customization of key parameters such as device name, baud rate, and pairing password, giving developers full control over configuration and communication behavior.
