Which boards are using Hashfast chips?
You can find that out by simply reading this thread.
HF Yoli, Habanero, and a couple of others use their chips.
It's not Uniquify's fault that HF failed, if that's what you're (passive aggressively) trying to imply.
I was hoping for an exhaustive list of the boards so I could compare specs, not just a few examples.
Clearly, you are not the resource to summarize the 11,000 replies from this thread. I shall look elsewhere.
