DCA1000EVM: My new DCA1000EVM board does not work. It draws 5 amps at 5 volts and all the LEDs are lit.

Please give us some time to review your question

Is the power supply you are using 5V/3A?

thank you

Cesar

I am using bench power supply which can give 6.5 amps at 5V.

If I use 5V/3A supply, voltage drops down to around 2.5V.

I think there is a short circuit maybe in the FPGA. Because it can draw 5 amps without voltage drop.

Also FPGA gets very hot and all the LEDs connected to FPGA are half lit which means outputs are floating I guess.

I have added a photo.

Any idea?

Should I return it?

Hello,

Has this board ever worked before?

It should not be drawing 5amps. There must be something shorted, most likely due to ESD damage. I would suggest trying to return it, it would be extremely difficult to diagnose and fix.
