Using EN05 with JLink? SWD pins not exposed?

Products & Technology XIAO
1

I just got a pair of EN05 ePaper boards delivered. I want to program them using my JLink, like I did with other XIAO boards.

Unfortunately, I can’t find the SWD pins.

Am I right in thinking that I’m out of luck?

The boards are v1.0

Thx

I am not 100% sure… but i think the bottom pads are brought out to the micro castalated pins.. you may be able to probe them

I didn’t think to check that. These “plus” boards are new to me.

Unfortunately, it doesn’t look like they are exposed :frowning:

It seems that the v1.11 revision of the EN05 has vias on the bottom, but I think I’m out of luck with my boards.

I think you can probe the micro-castalated pin at JTAG dark blue pins D12-15

Maybe my mistake… i thought i saw one running the S3 XIAO

We sincerely apologize for the inconvenience.
The EN05 you have is likely from the first batch of products. Based on user feedback, we subsequently added SWD pins, but this change will take effect in the next batch.

That’s the v1.11 revision? I spotted the vias in the KiCad PCB.

I will return these boards and wait until the next batch is in the wild!

Thanks you!
