I want to use the roboaudiostix and I have a 5V adaptor. However, I can't get a connector to fit it and apparently the power has to go directly to the roboaudio board. Would it be ok for me to use an ordinary regulator such as an lm7805? What is the current requirement? I want to use a connex with the roboaudiostix and a netMMC board. I do have another adaptor which gives 6V so was thinking of using this. What is the maximum voltage that can be fed to the roboaudiostix? Hope this hasn't been answered before... I'd appreciate any help.
