Adding additional layers for expansion on the 3pi+ robots

I was wondering if I can add another layer on top of the 3pi+. On the website, I wasn’t able to find any expansion boards that seem compatible with the 3pi+. Any replies are deeply appreciated.

Hello.

We currently do not have any expansion boards available for the 3pi+, but you might be able to mock one up with a prototyping PCB.
