Bộ 2 thiết bị thu phát Bluetooth HC-05

The factory setting is slave e, but you can set this ule to master e so that you might be able to connect to other Bluetooth 2.0 devices.HC-05 Wireless BT ule HC-05 Wireless BT ule: with this HC 05 Bluetooth ule,You can quickly add the Bluetooth feature to your Arduino project, and then you can use your android phone to control some gadgets, such as: switch, LED. Master and Slave 2-IN-1 HC 05 ule:Working Voltage 3.6V to 6V (prohibit exceeding 7V), Default baud rate:9600,Default pin:1234 Button: Press the button, the ule enter the AT e. AT commands are executed only in AT e. 6 PIN Dopunt Cable : with this Dupont Cable, you can easily connect this HC-05 Bluetooth ule to your Arduino Board ule parameters: 1. Leads 6 feet: EN/VCC/GND/RXD/TXD/STATE (Bluetooth state leads, not connected output low level, the output high level after connection) 2. With the connection status indicator, LED flash indicates no Bluetooth connection; Led slow flash indicates enter at command e 3. 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 4. Effective transmission distance of 10 meters in open area, more than 10 meters is possible, but not to ensure the quality of the connection Wiring method: VCC: Connect the power supply positive GND: Connecting the cathode RXD: The receiver, the Bluetooth ule receives data from other devices, and the sending end TXD of the other devices normally TXD: Send end, Bluetooth ule sends data to other equipment; the receiving end RXD of the other equipments normally En: To enable the end, need to enter the at e when 3.3V colour: blue Material: electronic components size: 37.3mm (length) x 15.5mm (width) Package Contents: 2 x HC-05 6-pin wireless Bluetooth RF transceiver ule for Arduino serial BT ule Note: this item doesn't works with iOS.
