Re: [Work in progess] Burnins Avalon Chip to mining board service

I wonder what would be the risk when a psu has for example 400W at one 12A line and i would power one board directly and 3 others with cables? I could use 3mm speaker cables if that helps...

You risk that the weakest part melts.
The power for the 3 others has to go through the PCB from the direct connection to the green terminal then.
burnin already recommended to only connect two boards and use solid wires. I would just follow his recommendations.

I wrote it in red and bold, USE SOLID COPPER WIRES
...

Question regarding that, that hasn't been mentioned.
If you are powering more than 2 of them through one power source, you are also running that current through the input voltage section of each of the boards.
Thus I imagine that could damage the boards also ... ?
i.e. really, don't do it with more than 2 ... ever ... for that reason also?
