Do you have 5V on the pins on the Octdopus you're trying to connect to?
Time to pull out the multimeter!
i think i do.. and ive never used a multi meter before lol.
Gotta verify, can't guess at voltage being present
so just to be clear. the power is supplied buy the usb? and the jumpers are for sending a signal to let the rpi know to use the usb?
no, the power is supplied by the Octopus, USB is for communication.
