TECNOULAB 5pcs HC 06 Bluetooth wireless module HC06 with slave base

【HC-06】The main module uses HC-06, the module interface wires include VCC, GND, TXD, RXD, spare LED status output pin, the microcontroller can be judged by the foot status. Bluetooth connected invalid slave KEY pin. 【Simple Operation】LED indicates Bluetooth connection status, flashing Bluetooth connectivity, activating Bluetooth connection and opening a door. Backplane.3.3V LDO input voltage 3.6 ~ 6V, the current is about 30mA unmatched, coupled about 10mA, the input voltage to prohibit more than 7V! Interface level 3.3v. 【Compact design】 Open to the effective distance of 10 meters, even more than 10 meters is also possible, but not from this, the distance connection quality guarantees. After paired, when using the full duplex serial port, there is no need to know nothing about the bluetooth protocol, it only supports 8 data bits, 1 stop bit, no parity communication format, which is the most widely used communication format, does not support other formats. Compact (3.57cm * 1.52cm) 【Compatibility】 with the Bluetooth connection. Subsequently the baud rate, the name, the password and the set parameters are saved. The Bluetooth connection automatically switches to transfer mode.
