Hello,

When the MMwaveICBoost was powered on,only one LED (D8) is on and we do not know the cause of this behaviour.

Please suggest on how to proceed.

Hi Zhang,

Thank you for the response.

Upon following the thread mentioned in the reply, we found that voltage on SOP jumper is not 3.3v

Please find the images of the board below.

Please let us know if there is any way to get the board back to working.

So the input voltage and output voltage of PMIC is not correct?

Hi Zhang,

Yes, voltage is not at 3.3v

Hi,

Since PMIC is broken. I don't think it is technical issues now, Try to contact sales or distributor.
