Modul bluetooth HC-05 hc05 BT UART RS232 TTL SLAVE MASTER Arduino

Specification:
Brand new
Input voltage: 3.6-6V
Working current: matching for 30 mA, matching the communication for 10 mA
Output Power Class: Class 2
Size: approx. 43 x 15mm
Color: blue & green, as picture shows
With VCC, GND, TXD, RXD, KEY foot for the Bluetooth
Led indicate Bluetooth connection status, fast flash indicates unpaired, slow flash indicates AT mode, double flash indicates machine connected
Backplane settings LDO input voltage of 3.6-6V unpaired current is about 30mA, paired 10mA, input voltage prohibit more than 7V absolute prohibition of reverse power
Interface level 3.3V, can be directly connected the various SCM (51, AVR, PIC, ARM, MSP430, etc.), the 5V MCU also can be connected directly, without MAX232 can not go through the MAX232
Open to effective distance of 10 meters, over 10 meters is also possible, but not of this the quality of the connection of the distance do to ensure
The pair later when full-duplex serial use, do not need to know anything about the
Bluetooth protocol, but only supports 8 data bits, 1 stop bit, no parity communication format, which is the most commonly used communication format does not support other formats
Support to establish a Bluetooth connection through AT commands set the baud rate, passkey, set parameters are saved after
