hi,

i'm very excited about your Lattice iCE40 base B serie.. i have a couple of questions..

let me say in advance that the "clever hack" for the minimal USB programmer step, is really appreciated, reducing the BOM a lot for a dev board.. i didn't see any led in place anyway, at least one as immediate feedback of a "running design" would be really useful IMHO. have i missed something? now back to questions..

what about programming your board with the yosys/arachne-pnr/icestorm FLOSS toolchain? did you try it? there's the added value that the 4K part could be "overlcharged a bit", as it looks like the 4k die doesn't really exist.. so B1 is a bit more compelling, provided you have the same $ margin..

then, where are the board supposed to be shipped from, actually? i live in EU/Italy and they charge a lot for customs over 20€ of the wriiten value on the bill. is a "sample/gift statement" someway unreasonable, eventually?

good luck for this prj!
