Description

HC-06 leads to interface includes VCC, GND, TXD, RXD, aside LED status output pin, the microcontroller via the pin state judge whether Bluetooth connection, KEY pin on the slave invalid

LED indicate Bluetooth connection status, flashes indicates no Bluetooth connection, Always indicate the Bluetooth port is connected and turned on Backplane 3.3V LDO, the input voltage 3.6 ~ 6V, unpaired when the current approximately 30mA, paired about 10mA, the input voltage must not exceed 7V! With interface level 3.3V, you can directly connect a variety of SCM (51, AVR, PIC, ARM, MSP430, etc.), 5V microcontroller can also be directly connected, it can not pass without MAX232 MAX232!
