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
||For configuration use (normally not
||3.3 to 5V input
||TX transmit pin
||RX receive pin

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.

* 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
* Via serial port, send characters "AT +
ROLE = 1 r n",if successful, return "OK r n",
where r n is carriage return.
