Description

1. The core module uses hc-06 slave module to lead out interfaces, including VCC, GND, TXD, RXD, and reserved LED status output pin. The single chip microcomputer can judge whether Bluetooth has been connected through the pin status, and the key pin is invalid for the slave
2. The LED indicates the Bluetooth connection status, flashing indicates that there is no Bluetooth connection, and constant light indicates that Bluetooth is connected and the port is opened
3. The backplane is 3.3V LDO, the input voltage is 3.6 ~ 6V, the current is about 30mA when not paired, about 10mA after pairing, and the input voltage shall not exceed 7V!
4. The interface level is 3.3V, which can be directly connected to all kinds of single chip microcomputer (51, AVR, PIC, arm, MSP430, etc.), and 5V single chip microcomputer can also be directly connected without MAX232
