Trouble with air unit

The air unit of the module is not switching on.

I have connected it with 7V DC regulated power supply but no response from Airunit.

When I plugged it with laptop through microusb cable the air unit is switching on and off continuously. With led 2 going orange and turning off.

I think i mistakenly had connected the power in reverse polarity :frowning:
Can you please help me out.

Check your power cable and see if it causes the problem.
Otherwise, the unit is mostly dead. You will need to contact your reseller
