I feel kind of sick seeing that people are using HashFast chips in third party projects. HashFast continues to screw it's customers over. I don't understand how members of this community are supporting them by making boards for HF chips.
Check out this thread, they actually ask a well-respected member of their chip partner company - HashFast_CL to shut up and leave. I wonder what they have to hide
