Thank for the guide Dogie. Allowed me to get familiar with the R-Box before even having it in my hand.

Plug and play with CGMiner 4.4.1 on rpi. Just added --rock-freq 290 and let it rip. This instance is also running 5 Antminer U2's @ 285Mhz.

my command line looks like this: sudo ./cgminer --rock-freq 290 --anu-freq 285 -o pool url -u username -p password

As a side note this rpi is also running an instance of Dmaxl's CGMiner 4.3.5 fork with 5 GAWminer Fury's using tmux to keep both instances alive and headless.
