LM25066EVK: LM25066EVK connection issue

Mac Aron

Part Number: LM25066EVK

I received a LM25066EVK - Evaluation board with a FT2232H mini module. The FT2232 comes with a 10 pin adaptor to connect to J1 of LM25066EVK. However the mini module and EVK board have reversed pinouts. Pin 1 connects to pin 2, pin 3 to pin 4 etc.

Hi Aron,

The issue we found is the Connector on this dongle is being soldered on the wrong side of the board. If we solder it back to the correct direction, the Dongle starts working as expected.

As you can see image below,

The board shown in the left hand side of the image has connector soldered in the wrong direction
The board shown in the right hand side of the image has connector soldered in the correct direction

We have already taken corrective action and all the new EVMs should have the connector soldered on the correct side.

Hi Praveen,

Thanks for the response. Is there someone I can contact to have a correct dongle shipped to me?
