Selamat Datang Di Toko Kami Semua Barang PreOrder 20-30 Hari Selamat Belanja Package : TQFP Model Number : HC-05 RF Wireless Bluetooth Transceiver Module Application : Computer Condition : New Type : Module Brand Name : diymore Origin : Mainland China PCB size : 37.3*15.5mm Input voltage : with 3.3V LD0 voltage regulator chip Product features: 1, the core module uses HC-05 from the module, the pin-out interface including VCC, GND, TXD, RXD, KEY pin, Bluetooth connection status pin (STATE), not connected to the output low, connected to the output high. 2, led indication of bluetooth connection status, fast flash means no bluetooth connection, slow flash means enter AT mode, double flash means bluetooth is connected and open the port. 3, the bottom board set anti-reverse diode with 3.3V LDO, input voltage 3.6~6V, current about 30mA when not paired, about 10mA after pairing, input voltage is prohibited to exceed 7V! 4, interface level 3.3V, can be directly connected to a variety of microcontrollers (51, AVR, PIC, ARM, MSP430, etc.), 5V microcontrollers can also be directly connected without MAX232 can not go through MAX232! 5, open space effective distance of 10 metres (power level CLASS 2), more than 10 metres is also possible, but does not guarantee the quality of the connection to this distance. 6, paired as a full-duplex serial port to use, without having to understand any Bluetooth protocol, support for 8-bit data bits, 1-bit stop bit, parity can be set in the communication format, which is also the most commonly used communication format, does not support other formats. 7, you can enter the AT command mode to set parameters and query information by pulling up 34 feet. 8, compact size (3.57cm * 1.52cm), factory patch production, to ensure the patch quality. And set of transparent heat-shrinkable tube, dustproof and beautiful, and has a certain anti-static ability. 9, can be switched to host or slave mode by AT command, can be connected to the specified equipment by AT command. 10Support the standard baud rate from 4800bps~1382400bps. Product use instructions Attention!!! Please do not connect the power supply to the signal pin, it will burn out directly! HC-05 Master-Slave Integrated Bluetooth Module Data Download: Product parameters: 1.PCB size: 37.3*15.5mm 2. Input voltage: with 3.3V LD0 regulator chip, 3.6V-6V, prohibited more than 7V 3. Power supply anti-reverse connection, the bottom plate set anti-reverse diode, reverse module does not work 4. 6 feet: VCC / GND / RXD / TXD / STATAE (Bluetooth status pin, not connected to the output of low level, connected to the output of high level) / EN (enable terminal, need to enter the AT mode when connected to the 3.3V) 1 small common sense (very important) TXD: transmitter, generally expressed as their own transmitter, normal communication must be connected to another device RXD. RXD: the receiving end, generally expressed as its own receiving end, normal communication must be connected to another device #39;s TXD. Normal communication when its own TXD always connected to the device #39;s RXD! Self-receiving: Normal communication when the RXD connected to the TXD of other devices, so if you want to receive the data sent by themselves as the name suggests, that is, they receive the data sent by themselves, that is, their own TXD is directly connected to the RXD, used to test their own sending and receiving is normal, is the fastest and simplest test method, when there are problems when the first to do the test to determine whether the product is faulty. Also known as loopback test. Level Logic: TTL level: usually data representation using binary, the provisions of the +5V is equivalent to logic #34;1 #34;, 0V is equivalent to logic #34;0 #34;, called TTL signal system, is the positive logic. RS232 level: using -12V to -3V, equivalent to logic #34;0 #34;, +3V to +12V logic level, equivalent to logic #34;1 #34;, is negative logic. Product usage: After pairing only need to be used as a fixed baud rate serial port can be used, so as long as the #34;fixed baud rate, 8-bit data bits, no parity #34; communication format of the serial port device can directly replace the original wired serial port without modifying the program. Such as data acquisition, intelligent cars, serial printers, outdoor dot-matrix screen control. Pairing with computers: Suitable for communication between computers and devices via Bluetooth serial port, using the same method as the serial port. Pairing with mobile phone: Suitable for communication between mobile phone and device through Bluetooth serial port, the use of the same method as the serial port. Pairing with Bluetooth host: Suitable for two devices to communicate directly through Bluetooth serial port, such as between microcontroller and microcontroller, wired serial port and microcontroller, etc., using the same method as the serial port. Adaptive use: Baud rate conversion, because the receiving end and sending end can choose their own baud rate, in
