Rasp pl did stupid moves on the new designs.

The new one uses a micro usb jack for power

Zero need to do it the larger mini usb is far better.

I would tell them WTF did you shrink the power jack.  The rasp pi is the same size zero need to shrink the power jack

I have had power issues feeding some rasp pi.

The micro sd was good idea as it is more protected the the larger sd card.
The newest rasp pi is pretty fast.  If they simply kept the bigger power jack it would work better.

As for software not enough of it for miners.
I do have Avalon s on it.

But that is it for now.
