IWR1443BOOST： the power light doesnot turn on

Part Number: IWR1443BOOST

I was using the device just now. I moved it halfway, but suddenly the power light turn off. No matter how I plug it in, there is no response and it doesnot work anymore.

Hello

Can you please confirm if the connectivity of the power pin is still intact.

Thank you for confirming that this board was working, please let us know if while moving there was any accidental short that might have led to board issue.

If possible please check the voltage on various device rails. See schematic for tap points.

Thank you,

Vaibhav

I confirm that the connection of the power supply pin is intact, because it was only a slight movement that won't cause damage to the pin, but I have no conditions to confirm whether there is a short circuit, what should I do？

Hello

Please check for the next mentioned in my previous post

Identify the tap pins for power supply to figure out what voltages are available. We do not expect a working board to stop working.

Please help us identify the issue - beginning with voltage rail values.

Thank you,

Please tell me which pins should be checked to determine if there is a short circuit

Hello

Please check the schematic for IWR1443boost to see the PMIC outputs. In either case if the board is not not working you may have to purchase a new board and use it with care so that similar issues do not occur.

Thank you,
