From waht I
understnad (and please correct me) the main 'IC' (Acutally a
multichip module I think) on the Rpi is one that was used in some other
large-prodcution device (smartphone?), and the Rpi is using the
'leftovers'. Part of the datasheet on this IC is covered by an NDA. Err,
no thanks. And I am worried that the supply of these ICs will dry up. I
am not goign to waste my time designing soemthign roudn a board that
won't be available when I want to make more of them.
Well, yeah. The entire budget of the project is basically built on
volume, since that drives the cost of silicon down. Broadcom won't
even deal with you unless you're planning to make tens of thousands
of units (or have REALLY deep pockets, like one of our customers).
I think the entire release of the board was made possible only
because one of the founders works at Broadcom and co-developed the
SoC that serves as the CPU.
I don't know about the "leftovers" part. They must have had a LOT of them
if so - while the first batch was 10,000 units, they've gotten orders for
at least 400,000 and they're well on the way to meeting (or have already
met) those orders now.
Frankly, I love the stupid little thing. It has huge potential to affect
my "main" hobby by driving down the prices of flight simulator avionics
for the hobbyist. :)
