Thanks, zefir - I was just trying to remind Giorgio that he said he was going to update the spec today... there are a lot of unanswered questions that impact any board design.... and if you expect orders only from DIY's who will assemble chips like that to boards themselves, I suspect you will have little call for chips - hot-air/infrared assembly is not for the inexperienced or the faint of heart, and at over $100/chip, the risk is quite high. I think I will take your advice, and put a hold on the order that I sent you earlier this morning. It's mostly wasted effort, after the buck controllers and microprocessor are laid down, until the real specs arrive. The window hasn't closed on getting boards fabbed and assembled (omitting A1's) by the time the chips turn up - I was going to HARW them onto two already assembled boards, so I've got some time yet...

Here's hoping Giorgio (or rather one of his engineering minions) gets some free time soon....
