Bluetooth module HC-06 transceiver UART

Features

100% brand new and high quality HC-06 bluetooth RF transceiver module
With VCC, GND, TXD, RXD foot for the bluetooth.
With LED indicator light.
3.3V LDO baseboard.
Input voltage 3.3-6V, the input voltage more than 7V is prohibited.
Unpaired current is about 30mA, matched current is about 10mA.
Interface level 3.3 V, can be connected directly to a variety of single chip microcomputer (51, AVR, PIC, ARM, MSP430, etc.)
5V microcontroller can also be connected directly, without MAX232 nor through MAX232.
Open to effective distance of 10 meters, over 10 meters is also possible, but not of this the quality of the connection of the distance do to ensure
The pair later when full-duplex serial use, do not need to know anything about the Bluetooth protocol, but only supports 8 data bits, 1 stop bit, no parity communication format, which is the most commonly used communication format does not support other formats.
Support to establish a Bluetooth connection through AT commands set the baud rate, passkey, set parameters are saved after. 

Specifications:
