Re: [OPEN] Bitmine CoinCraft A1 28nm chip distribution / DIY support
This. The sample chips need 850mV min, not sure if the chips from the production batch are better suitable for down-volting - but obviously everybody is looking to up-volt them anyway 
Oh... I tried it to use 0v7 ~ 0v765 for safe testing....
I see that why my chips return very small level signal...
Thank you Zefir, I'll try it in 0v85.
