When you buy chips you need like an engineer to make the project than an expert who assembles miner.
PS: not every chips will work as you expect.
true.- electronical worker that it can build the FTDI interface and voltage control and regulator (with an expensive software to root the track).
- chimistery worker (factory) that it can sold with wave, the card
- same or other chimistery that it can apply the isolator or multiple layer
... and all of this ? IT VERY expensive for a private consumer ... because, me, i build somes PCB with picaxe for batteries monitoring (i known the price of this work).
