AITIAO 3Pcs HC-06 RS232 4 Pin Wireless Bluetooth Serial RF Transceiver Module Bi-Directional Serial Channel Slave Mode

AITIAO 3Pcs HC-06 RS232 4 Pin Wireless Bluetooth Serial RF Transceiver Module Bi-Directional Serial Channel Slave Mode

Working voltage 3.6V to 6V; Default baud rate : 9600 Pairing code : 1234; Host Interface:UART Works with any USB Bluetooth adapters, running in slave role: Pair with BT dongle. Core module uses HC-06,wire from the module interface includes VCC, GND, TXD, RXD, reserve LED status output pin, the microcontroller can be judged by the foot state Bluetooth has connected KEY pin slave invalid. The HC-06 bluetooth module allows your device to both send or receive the TTL data via Bluetooth technology without connecting a serial cable to your computer. It is mainly used for short-range data wireless transmission,such as Bluetooth wireless data transmission,Industrial remote control, telemetry,Traffic, underground positioning, alarm,Smart home ect.

Feature: 

1. With LED indicator light, use 150mA and 3.3V regulation chip.
2. With VCC.GND.TXD.RXD foot for the Bluetooth
3. With "Re-seach" button(ON/OFF/WAKE foot for it , external MCU outinput "High level" can control module to re-seach)
4. Compatible with bluetooth master module".slave module"or master-slave(whole) module.

Please note:

1. Input power supply 3.3~6V, Prohibit more than 7V
2. No "Automatically prevent power supply peversing func", so please correctly connect power supply
3. We advise to install "Bluetooth master module"
4. The "State" is output foot for LED status, when bluetooth "Unconnected", output "Pulse" ; when bluetooth "connected", output "High level", we can determine the states from "MCU"
5. If only the board , No any "Bluetooth Function"
