Key Features

• ✅ Master-slave integration 2-IN-1 HC-05 Module: the original chip corresponds to the master-slave integration function. Master-slave integration can switch between master and slave modes. Through AT command setting, you can select master mode or slave mode.
• ✅ AT Setting: Press the button and power on the module to enter the AT mode. AT commands are executed only in AT mode, which is easy to use. Default baud rate:4800,Default pin:1234, the default name is HC-05.
• ✅ On-board 3.3V voltage regulator chip, input voltage DC 3.6V-6V; When not paired, current about 30mA (due to LED lights flashing, current in the state of change); After the pairing succeeds, the current is about 10mA
• ✅ Working status indicator: Fast flashing LED means no Bluetooth connection, slow flashing means entering AT mode, double flashing means Bluetooth is connected and the port is opened.
• ✅ Tips:Do not connect the power supply to the signal pin, otherwise the module will be directly damaged. The input voltage must not exceed 7V. (Note: this item doesn't works with iOS.)
