WROOM32 v1.0 vs v1.1 different trace antenna layout
Posted: Wed Jun 21, 2017 7:39 pm
Hi guys,
While designing our next gen product, we found out that WROOM32 actually have two different trace antenna layout.
This really creates problems for our PCB design. We will be using an extern antenna with our product and really need to make sure want have the test points at the right place.
We sourced our esp32s from taobao and it seems all of them have the v1.0 design. It also might be the case that some of them do have v1.1 design but their artworks haven't been updated ?
Can anyone from within expressif confirm which layout is the most current one and from where we can source the version reliably?
Best regards,
-jake
