Oh thanks for pointing this out, this was simply forgotten on the product description page. Of course, this is possible - in the meantime until the shop-page is updated you can write directly to shop (at) nitrokey (dot) com with the configuration you would like to have and we will sent you a offer accordingly. For HEADS + Nitrokey 3, yes this is completely working, if you buy a Nitropad with a Nitrokey 3 now, it's in stock and no further delay is expected.
