Hello Pete,

Really happy to hear you are working on this issue. Unfortunately I cannot help with this issue, but I try to ping mantonakakis, he managed to get low power mode working.

Hello, Pete,

Are the revised boards in production? I got my SAMDs about a month ago: any chance that they are the revised boards, and how would I identify those? Even the reduction to 460µA in low power mode would be a big help. I have to admit to being a little nervous about cutting the VDDCORE trace, if that’s what I’m going to need to do, and I do intend to run off battery.

Are the revised boards in production?

  • Not yet, but they are coming! Lots of ducks to get in a row to get the revision live on the website.

    • how would I identify those?

  • They will have a new SparkFun part number and once the old board is retired, it will link to the new board. You will see this come out on a Friday in our 'New Product' posts when they are ready to go.
