HC-06 Serial Bluetooth Module
HC-06 Serial Bluetooth Module
This is a full-duplex serial Bluetooth module. It does not require users to understand any Bluetooth protocol. It only needs to connect the Bluetooth module to the serial port of the MCU (such as Arduino) to complete the Bluetooth communication function.
<>Features:
- • Input voltage: 3.6~6V
- • Communication distance: 10m
- • Default baudrate: 9600
- • Bluetooth protocol: 2.0
- • Size: 37.3x15.5mm
<>
Pinout:
- • VCC: Positive power supply, 3.6~6V
- • GND: Power negative
- • RXD: The Bluetooth module receives data from other devices
- • TXD: Bluetooth module sends data to other devices via TXD
- • EN: Connect to 3.3V to enter into AT mode
<>
AT command:
In the case of not completing the pairing, the module works in AT mode. The default baud rate is 9600, the module Bluetooth name linvor, password 1234
