Module Bluetooth HC-06 HC06
HCHC06 is a slave Bluetooth device that offers serial communication (UART). Hence, a master is required to establish a successful wireless interface. The module has only communication and power pins. Please note that some HC-06 module may have 6 pins. But only 4 of them are used.
|PIN NO.||Pin Name||Description|
|1.||VCC||Used to power the module. Connect it to a 3.3V pin of the microcontroller.|
|2.||GND||Connect this pin to the common ground of the circuit.|
|3.||TXD||Connect this pin with the RXD pin of the Microcontroller. This pin transmits Serial data (wireless signals received by the Bluetooth module are converted by module and transmitted out serially on this pin)|
|4.||RXD||Connect this pin to the TXD pin of the Microcontroller. The HC-05 Bluetooth module receives the data from this pin and then transmits it wirelessly.|
