As other reviewers have pointed out, Matthias is a great communicator and is always fast to respond. The TC4+ shield is a really nifty device with everything the coffee roasting enthusiast needs to start profiling and even automating parts of the roasting process. The documentation it comes with is clear, thorough and takes you through each step of the process. It's so well written that even I, a complete Arduino newbie could get everything setup without too much bother. I did run into some issues setting up the optional bluetooth transmitter (issues of my own making), but Matthias had seemingly infinite reserves of patience in helping me diagnose the issue.
Great device, thoroughly recommend buying from this seller. You can't go wrong!
I ordered the pre-assembled version. In fact, as the SMD components would have been soldered on in the kit version, I would probably haven't had a problem assembling it myself, as good as all quality is.
The shipping was fast, though I experienced a delay thanks to Brexit and COVID. In this light, it was great that I could reach the seller, who answered quickly.
The part itself is very satisfactory. It's well thought-out, offers a lot of options, is very well supported in Forums and Github repositories, and has a community you always get help in. The written documentation comes in several detailed PDFs.
This is a great little board for those starting out on the road to coffee roasting. The instructions come as a pdf and give you all of the detail for building your first air roaster. I was so encouraged how well it worked I'm now building something more adventurous!
The communication has been great and there are a load of forums out there with plenty of advice and ideas. Oh, and there's nothing quite like your own freshly roasted coffee in the morning.
This is a very well-designed board that is a huge convenience to the amateur coffee roaster. Use it with virtually any popcorn machine because it's so versatile. The guy that makes it is very knowledgeable and very helpful, the support is off the hook! You really can't go wrong with the TC4+
I'd suggest to provide as add-on even more components for those using this board with a popper, e.g. a pair of TC and an SSR.
It would also be helpful to have a printout of the most common board setup, or at least a short URL pointing to the basic setup.

Thank you for your kind review, Marco. And thank you for your suggestions! I am already planning to make further components available with the board! Stay tuned. A quick-start guide is also coming soon. :)
