We are figuring that there will be some gigantic parts availability crunches pretty soon. There have be self-fueling parts panics before this current supply-chain nightmare. So we are working on buying some critical parts now, before the crunch.
So, can anyone guess what parts are most likely to be hard to get? We may as well buy reels of the common cheap stuff. I design with a lot of 1 uF ceramic caps and a few preferred surface-mount resistor values, which are cheap, so we'll get lots of those.
I'm thinking FPGA and uPs and other chips that have no simple substitutions.
