| ● | Core module HC-05, leads from the module interface including VCC, GND, TXD, RXD, KEY pin and LED Status pin-out (STATE) |
| ● | Led indicate Bluetooth connection status, flash Bluetooth connectivity slow flash into AT mode, double flash Bluetooth connection and open a port |
| ● | Backplane set anti-reverse diode with 3.3V LDO input voltage of 3.6 ~~ 6V unpaired current is about 30mA paired approximately 10mA input voltage to prohibit more than 7V! |
| ● | The interface level 3.3V direct connection the various SCM (51, AVR, PIC, ARM, MSP430, etc.), the 5V MCU also can be directly connected, without MAX232 can not go through the MAX232! |
| ● | Open to effective distance of 10 meters, more than 10 meters is also possible, but not this distance connection quality assurance |
| ● | When paired with full-duplex serial port to use, do not need to know anything about the Bluetooth protocol support 8 data bits, 1 stop bit, parity can be set communication format, which is the most commonly used communication format does not support other formats. |
| ● | Can be pulled up 34 feet into the AT command mode to set parameters and query information |
| ● | Compact (3.57cm x 1.52 cm), chip production factory guarantee placement quality. And sets of transparent heat shrink tubing, dust and beautiful, and anti-static. |
| ● | Available through AT commands switch to host or slave mode via AT commands access the specified device |
| ● | Supporting standard baud rate from 4800bps ~ 1382400bps |
Usage:
After pairing only need as fixed baud rate of the serial port as can be, so long as it is "fixed baud rate, 8 data bits, no parity" serial communication format equipment can be a direct replacement for the original wired serial port without the need to modify the program. Such as data acquisition, smart car, serial printer, outdoor lattice strip screen control.Paired with computer use: for computers and devices via Bluetooth serial communication, use serial paired with the phone use: suitable for the mobile phone with the device through Bluetooth serial communication, use serialpaired with the Bluetooth host: for the two devices directly through the Bluetooth serial communication between the microcontroller and the microcontroller wired serial interface with microcontroller between use with serial
