HC-06 Wireless Bluetooth Transceiver Module Compatible version

Description: The main modules of the HC-06 basic unit, drive the interface including VCC, GND, TXD, RXD, and KEY pin high trigger to clear pairing information and search back. The LED indicator shows the Bluetooth connection status, with slow flashing when unpaired indicating the slave is not connected, and steady flashing indicating the paired slave. Always follow the device connection and back panel LDO settings. Input voltage from 3.6V to 6V, unpaired current about 30mA, paired 10mA. Input voltage must not exceed 7V; absolutely prohibit reverse power! Interface level is 3.3V, can be directly connected to various microcontrollers (51, AVR, PIC, ARM, MSP430, etc.), 5V MCUs can also be connected directly, without MAX232; passing through MAX232 is not possible. Effective communication distance is 10 meters, more than 10 meters is also possible but may affect connection quality. To ensure full-duplex serial pairing later, no need to know Bluetooth protocol, only supports 8 bits, 1 stop bit, no parity, the most common communication format, other formats are not supported. Supports establishing Bluetooth connection via AT commands to set baud rate, passkey, and save parameters. The Bluetooth connection automatically switches to scroll mode. Wireless serial Bluetooth port with free extension cable. Comes with transparent, dustproof, attractive shrink tube, and has certain anti-static capabilities. Size: 3.57 cm * 1.52 cm. Tips: TXD: Transmitter, usually called transmit, must be connected to another device's RXD for normal operation. RXD: Receiver, usually called receive, must be connected to another device's TXD for normal operation. Package includes: 1 x HC-06 Wireless Bluetooth Transceiver
