Barntech (or anyone), can you state about the USB connector on drillbit-8 boards?
Is it USB-A socket, USB Mini-B, Mini-A, micro, ... else?
I searched for that and nothing pops up, and the picture of board is not so helpful. Initially I assume this is USB-A socket, then looking at picture it is more likely a USB mini-B. Still, we don't have accurate info about this point.
Also I read that we just need to plug one board among 4 to control system, when they're stacked on a miniplane. Is it still right? So hub is only required for multiple miniplanes.

The socket is USB mini-B, and yeah you only need to plug one board in to connect the entire miniplane (or double scroll), only requiring a hub if you are going to be pluggin in lots of miniplanes.
So, do we need 1 USB to USB Mini-B to connect our mini plane to our e.g. Raspberry Pi? (Or for those with more mini planes, just 1 USB Mini-B for their larger double scroll?)
Thanks,

It depends on if you want the devices to be treated as one or a separate when on the mini plane. It said you can use 8 individual cables and treat them like usb devices. I'm still going to want to see how many shares one takes to see if I want to do either way.
Ah, I see what you mean. I will overclock them together and send the BTC produced to the same pool, so imagine one is enough.
Not a bad way to compare pools though, just set up 2 per pool (from 4) and see which pool does the best. (Perhaps having a few extra on hand is a nice experiment).
Thx for the reply,

Just to clarify for the less technical of us:
Power - direct connect to a standard modular ATX PSU?
Mini USB - connect to computer or pi
This is for mining software and internet connect? So we will need a cord with Mini USB on one end and standard USB on the other right?
Individual board powered by a 4 pin molex connector, mini plane via a 24 pin atx connector, as far as I know.
That is my understanding as well.
And Swimmer63 - It is a Mini-B to USB yes (and yes, from the Raspberry Pi to the back plane or 8 chip card). And yes, it is for the Raspberry Pi to communicate with the miner via it's software. My technical expertise is years behind me btw. Getting a Raspberry Pi is the first time in years I've done sysadmin or Linux type work...

We should also find the right kind of cable for USB mini B to standard so everyone can click on NewEgg or Amazon or something.
And list all the commands needed for cgminer or the like.
This may be all in the previous pages but I'm not an IT guy so my eyes start to glaze over some of these posts.

... still quite a few outstanding btw), i have found us a new PCB manufacture factory and a new assembly house that will turn things around much faster. It will cost a bit more, but worth it to get these things happening quicker.
