FRWY-LS1046 J67 Connector Pinout

matthej — Fri, 05 Feb 2021 19:17:18 GMT

On the FRWY-LS1046 eval board getting started guide, figure 4 on page 5 shows a picture of this evaluation board. If you zoom closely it shows the pinout of J67 connector as follows:

2 1

4 3

etc, but the actually board shows the connections as

1 2

3 4

etc. Which is the correct pinout of J67?

Thanks,

Matty

Can someone please help? I received an email back from NXP asking for clarification which I sent back in an email. But anyway here is the issue:

The acutal board which I have shows the pinout for the J67 connector as

1 2

3 4

etc.

If I look at the photo on the FRWY getting started guide the photo on there shows

2 1

4 3

etc.

Please verify which is correct?

Thanks!

Here is the photo of the actual board. You can clearly see that the pinout is reversed. Look at pins 19 and20 on J67
