Thanks for your positive feedback. When I first saw your post title, I thought you mean your DIY board was fried or something, which scared me 🙂
Regarding the expansion boards, it’s unlikely the DIY version will be offered again. I am trying to consolidate the number of products and versions in order to reduce the overhead. For the expansion board, I may consider offering just the PCB and then provide Digikey links to the components. This should be easy to prepare.
