Sell Arduino HC-05 HC05 Wireless Bluetooth Serial Port Module best price

HC-05 master-slave integrated Bluetooth module With Clear Key Warm Tip: Do not connect the power to the signal foot, it will burn the module directly. Make sure every module is well tested. Low profit, no technical support and refund and exchange service Before buying, please consider clearly! Module parameters: 1. PCB size: 37.3mm (long) * 15.5mm (wide) 2. Weight: 3.5g 3. Input voltage: 3.6V-6V, prohibit exceeding 7V 4. Power supply anti-reverse connection, anti-module does not work 5. Lead out 6 feet: EN/VCC/GND/RXD/TXD/STATE (Bluetooth state lead-out foot, output low level without connection, output high level after connection) 6. With connection status indicator, LED flash means no Bluetooth connection; LED slow flash means entering AT command mode. 7. On-board 3.3V voltage regulator chip, input voltage 3.6V-6V; without matching, current is about 30mA (due to flashing of LED lamp, current is in a state of change); after matching success, current is about 10mA. 8. The interface level is 3.3V, which can be directly connected to various microcontrollers (Arduino/51/AVR/PIC/ARM/MSP430, etc.) and 5V microcontrollers can also be directly connected. Direct connection to single chip serial port, can not go through MAX232 chip! 9. Effective transmission distance of 10 meters and more than 10 meters in open space is also possible, but the quality of connection is not guaranteed. 10. When the pairing is successful, it can be used as full duplex serial port. It does not need to know any Bluetooth protocol, but only supports 8 bit data, 1 bit stop bit, no parity check communication format. This is also the most commonly used communication format, does not support other formats! 11. Press the button and power the Bluetooth module to enter AT mode, set parameters and query information. 12. Host and slave mode can be switched by AT command 13. The default baud rate of the module is 9600, the default paired password is 1234, and the default name is HC-05. 14. Protection with transparent heat shrinkable tube 2. Wiring method: VCC: Connect power supply positive pole GND: Connecting Power Negative RXD: Receiver, Bluetooth module receives data from other devices; TXD, which normally receives data from other devices TXD: Sender, Bluetooth module sends data to other devices; Receiver RXD normally connects to other devices EN: Enabler, 3.3 when required to enter AT mode We deal in wholesale and retail Feel free to contact us #HC-05 #HC05
