SKU: IFT00083-1 Category:


The Bluetooth Module Breakout is the latest Bluetooth wireless serial cable! This version of the popular Bluetooth uses the HC-05/HC05/HC-06 module. These modems work as a serial (RX/TX) pipe. Any serial stream from 9600 to 115200bps can be passed seamlessly from your computer to your target. The remote unit can be powered from 3.3V up to 6V for easy battery attachment. All signal pins on the remote unit are 3V-6V tolerant. No level shifting is required. Do not attach this device directly to a serial port. You will need an RS232 to TTL converter circuit or Arduio XBee USB Adapter if you need to attach this to a computer. You can either solder a 6-pin header or individual wires. Unit comes without a connector. Please see related male and female pins below. And now, we provide HC-05/06, HC-05 could be setting to Master or Slave by user.


Coupled Mode: Two modules will establish communication automatically when powered. PC hosted mode: Pair the module with bluetooth dongle directly as virtual serial.

Bluetooth protocal : Bluetooth Specification v2.0+EDR Frequency : 2.4GHz ISM band Modulation : GFSK(Gaussian Frequency Shift Keying) Emission power : <=4dBm, Class 2 Sensitivity : <=-84dBm at 0.1% BER Speed : Asynchronous: 2.1Mbps(Max) / 160 kbps, Synchronous: 1Mbps/1Mbps Security : Authentication and encryption Profiles : Bluetooth serial port

CSR chip : Bluetooth v2.0 Wave band : 2.4GHz-2.8GHz, ISM Band Protocol : Bluetooth V2.0 Power Class : (+6dbm) Reception sensitivity: -85dBm Voltage : 3.3 (2.7V-4.2V) Current : Paring – 35mA, Connected – 8mA Temperature : -40~ +105 Degrees Celsius User defined Baud rate : 4800, 9600, 19200, 38400, 57600, 115200, 230400,460800,921600 ,1382400. Dimension : 26.9mm*13mm*2.2mm

Pin definition :

* PIO8 connects with LED cathodea with 470ohm series resistor in between. LED NEGATIVE connects to ground. It is used

to indicate the module state. After powered on, flashing intervals differ in different states. * PIO9 is used to control LED indicating paring. It will be steady on when paring is successful. * PIO11, module state switching pin. HIGH -> response to AT command; LOW or floating -> regular work status. * With build-in reset circuit, reset is completed automatically after powered on. * Steps to set to MASTER: * Set PIO11 HIGH with a 10K resistor in between. * Power on, module comes into AT Command Response Status * Open HyperTerminal or other serial tool, set the baud rate 38400, 8 data bits, 1 stop bit, no parity bit, no Flow

Control:- * Via serial port, send characters “AT + ROLE = 1 r n”,if successful, return “OK r n”, where r n is carriage return. * Set PIO11 LOW, re-power, then in Master state, automatically search for slave module and connect.
