I’ve been tinkering with an idea for a general-purpose base/carrier board for the Adafruit Itsy Bitsy M4.
The idea is to have an Arduino-like system that allows stacked boards to be addressed and also allows for small amounts of IO circuitry to be connected to the edges of the main PCB.
Maybe this video will help explain.
I don’t show the “walls” in the vid because they are not designed yet for this version, but here is a photo of a previous version that is very similar.
I just sent V2 of the new design off to PCBway, I will load a couple of them and see how they work, based on that I’ll decide if I want to continue with the project.
Anyway I thought you guys might find it a little bit different to other offerings currently available. It will be open source but apart from a networked monitoring system for my solar system it’s just a bit of fun for me that helps me keep my design hand in.
