"Can Buy It Now in my ebay store"



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.

6) Enjoy


Basically, user can only use 2 to 5 pin in most of the application

1 KEY For configuration use (normally not connected)
2 VCC 3.3 to 5V input
3 GND Ground
4 TXD TX transmit pin
5 RXD RX receive pin
6 STATE  Connection status

Industrial serial port bluetooth, Drop-in replacement for wired serial connections, transparent usage. You can use it
