You said the Block Erupter Controller Board requires a 12V 1A minimum. Although on my Block Erupter Controller is labeled 5V on the outside. Which is right?
There's whole swaths of posts about this very subject in this very thread.
I have no idea who was responsible for labelling the cases as 5V.
The DC/DC chip on ethernet controller handles inputs from 5 to 12V. We tested cases of 5V and 12V and both work.
you can use 5V or 12V
but amperage must be at least 12W so 5V 2.5A or 12V 1A
This. More likely to drop out at 5V as well.
