Qty

Details:

Core Modules using HC-05 slave modules,leads from the module interface including VCC, GND, TXD, RXD. Reserve LED output pin status,Single Chip Microcomputer can be judged connected or not by the foot state,KEY pin is invalid for slave.
LED indicate show connection status,when it is flashing means non-connection, normally on mean it connect successfully
Backplane set anti-reverse diode with 3.3V LDO, input voltage: 3.6~6V , Unpaired current: about 30 MA, Paired: about 10 MA, input voltage cann't exceed 7V
Interface level 3.3V, can be directly connected the various SCM (51, AVR, PIC, ARM, MSP430, etc.), the microcontroller can also be directly connected without MAX232
Effective distance : 10M
After repaired,can used as full-duplex serial,supports 8 data bits, 1 stop bit, no parity communication format
Easy to connect this module with any standard Bluetooth device, just search and key "1234" passcode.
Running in slave role: Pair with BT dongle and master module,Simply establish connection between device with bluetooth function GPS, PC,PDA,PSP phone ,Industrial control,etc.
