Ah yes, I am already using a current-sensing chip - MAX4378 (which is very much similar to the ones you specified, i.e. it is based on op amps), However, I need to run the power source through the chip and then to the BBB.
I was wondering what would be the best way to do this? Do I attach the two wires to a power jack connector and then plug it into the 5V input or is there a better way? Please do correct me if I'm wrong. Thanks, Jayson On Wednesday, April 2, 2014 8:44:46 PM UTC+1, Gerald wrote: > > I would look at these type devices.
