AWR1642BOOST: AWR1642BOOST

Hello, 

The EVM is rated to work with a 5V supply as also indicated in the user's guide AWR1642 Evaluation Module Single-Chip mmWave Sensing Solution User's Guide (Rev. C). In this case, the PMIC and some of the components in the path might have been damaged by your supply.

Hi Aydin,

Thanks for the reply.

if these components got damaged, How do we replace damaged comments and How do we check it.

Do you have any idea about checking this components. where do i send this board to fix it?

Hello,

You can try to debug by downloading the design files from the product page and locating the components from the layout file. Once that is done, you can try to power on with a 5V supply, probe at the PMIC's input and output and check the voltage. If the output voltage from the PMIC is good, you can try to check the bandgap voltage on the Radar. If the PMIC is down, you could try replacing the PMIC. 

Regards.

Hello,

I will have checked it.

How do I replace a damaged PMIC integrated with the board? I want to send it to TI for a replacement. Who should I contact for processing?
