Keywords:HC-06 Bluetooth module with baseboard
1) Wireless serial bluetooth port.
2) With free power adapter bottom board come with well power regulator.
User can connect 3.3 to 5VDC and connect TX and RX to your control IO (general 3.3 to 5V digital input output of MCU or arduino IO is ok, or general TLL IO)
3) Easy to connect this module with PC, just search and key "1234" passcode.
4) With white SMD LED on the adapter board, can see the Bluetooth connection status.
Step to connect:
1) Connect the wiring, power up, while the device is not connected, the bluetooth module board has a white LED flashing
2) At PC side, search bluetooth device.
3) Found name called "LINVOR" device
4) Connect it, and passcode is "1234"
5) While connection is ok, you can see the LED become always on.
Basically, user can only use 2 to 5 pin in most of the application
Industrial serial port bluetooth, Drop-in replacement for wired serial connections, transparent usage. You can use it
simply for a serial port replacement to establish connection between MCU and GPS, PC to your embedded project and etc.

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
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.
