HiLetgo HC-05 Wireless Bluetooth RF Transceiver Master Slave Integrated Bluetooth Module 6 Pin Wireless Serial Port Communication BT Module for Arduino
<b>Module parameters: </b><br> 1.PCB Size: 37.3mm (Long) *15.5mm (wide) <br> 2. Weight: 3.5g<br> 3. Input voltage: 3.6V--6V, prohibit exceeding 7V<br> 4. Leads 6 feet: EN/VCC/GND/RXD/TXD/STATE (Bluetooth state leads, not connected output low level, the output high level after connection) <br> 5. With the connection status indicator, LED flash indicates no Bluetooth connection; Led slow flash indicates enter at command mode<br> 6. 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<br> 7. Effective transmission distance of 10 meters in open area, more than 10 meters is possible, but not to ensure the quality of the connection<br> 8. After pairing succeeds, can be used as full duplex serial port. No need to understand any Bluetooth protocol, but only support 8-bit data bits, 1-bit stop bits, no parity communication format. This is also the most commonly used communication format, does not support other formats! <br> 9. Press the key and then power up the Bluetooth module to enter at mode, set parameters and query information<br> 10. Can switch host and machine mode from at command<br> 11. The module default baud rate is 9600, the default pairing password is 1234, the default name is HC-05<br> <b>Wiring method: </b><br> VCC: Connect the power supply positive<br> GND: Connecting the cathode<br> RXD: The receiver, the Bluetooth module receives data from other devices, and the sending end TXD of the other devices normally<br> TXD: Send end, Bluetooth module sends data to other equipment; the receiving end RXD of the other equipments normally<br> En: To enable the end, need to enter the at mode when 3.3V<br><br><b>Note: this item doesn't works with iOS.</b><br><br><b>Package included: </b><br> 1* HC-05 6 Pin Wireless Bluetooth RF Transceiver Module Serial BT Module for Arduino<br>
