HC06 HC-06 Wireless Serial 4 Pin Bluetooth RF Transceiver Module RS232 TTL bluetooth module H34

Pay special attention to; The following are wrong connection methods:   Of the following does not belong to quality problems, are all wiring error, not warranty caveat emptor: 1, since the voluntary testing after the success, the use of TXD or RXD and short circuit 2, module meet the power supply cause damage   Product features: Using HC - 06 from module 1, a core module, which leads to the interface includes VCC, GND, TXD, RXD, reserved LED state output pin, MCU can state whether the bluetooth is connected through the foot, from machine KEY pin is invalid 2, the led indicates a bluetooth connection status, twinkle said there was no bluetooth connectivity, Chang Liang said bluetooth is connected and turned on the port 3, backplane "3.3 V, the input voltage 3.6 ~ 6 V, current when the unpaired about 30 ma, matching after about 10 ma, no more than 7 V input voltage! 4, interface level 3.3 V, can be connected directly to all kinds of single chip microcomputer (51, AVR, PIC, AR
