Hi,

Looking for advice on using a Sparkfun Beefcake with a Raspberry Pi - wondering if I can use the 5volts from the Pi for the 5volts on the Beefcake, the Ground from the Pi to the Ground from on the Beefcake, and then one of the GPIO pins (3.3 volts) for the 'signal'.

I've seen conflicting reports about controlling Relay boards from a Raspberry Pi, and hoped this might work for the Beefcake?

All insights gratefully received.
