I've already contacted them using their online order form to ask about these. I'll see if I get any reply. I'm a bit worried, since the fields in the order form seem to indicate they are looking exclusively to sell these cores to literal OEMs, not hobbyists. They have a field for example where I can put my company name, and there is an asterisk by it, meaning it is mandatory to fill it in (meaning they only want people who are actual manufacturers, who will use this core in a product, to contact them about it). I simply put "none" in that field (and similarly bypassed other mandatory fields that ask about details about my company). I'm concerned I may get no reply from them. If I do get a reply though, I'll post back here and let you know.
