3.3V Wireless Bluetooth Board Slave RF Module HC06 4 pin Transceiver RS232/TTL for Arduino

Features:

• 1, The core module HC06 Slave module , 4Pin Serial ;
• 2, LED indicate Bluetooth connection status , flashes to indicate there is no Bluetooth connection, Stable Lighting indicates Bluetooth paired connection ;
• 3 ,DC 3.3V LDO, the input voltage 3.6 ~ 6V, recommended 3.3V-5V stable power supply ;
• 4 , The interface level is 3.3V, can directly connect a variety of SCM (51, AVR, PIC, ARM, MSP430 , etc. ) , then the microcontroller does not need to go through MAX232 level converter , if connected with computer RS232 interface , need to add MAX232;
• 5 , Clearings effective distance: 10 meters
• 6 , After connection, when using full-duplex serial port, without having to know any Bluetooth protocol, but only supports 8 data bits, 1 stop bit, no parity serial format
• 7 , When Bluetooth connection is not established, support set the baud rate, the name, the pairing password via AT commands, parameter Power-down save. After connecting the Bluetooth, can automatically switch to pass-through mode

• STATE: status indicator pin, which can be accessed microcontroller to detect whether the module connect to other Bluetooth devices;
• VCC GND: power input, which can be accessed 3.3V-5V voltage;
• RXD: the receiving end, connected to TXD of others serial devices ;
• TXD: the sending end, connected to RXD of others serial devices ;
• KEY: Memory clear pin, when the Bluetooth module is powered up, it will automatically search the last paired Bluetooth devices, if the CLR pin is connected with 10US level or more, can clear the pairing information of the Bluetooth module;

• 1x Bluetooth Slave Module
• 1x 4P line
