CM2302 power cosiderations
In my new project I want to place the CM2302 module outside, and have it connected to the Activity Board using some four wire telephone cable, which will be located inside the house.
Now the questions is, since the cable will be at least forty feet in length, will the Activity board be able to supply the necessary power. I am not sure as to how much power it will cost to deliver the necessary voltage over forty feet of wire. The telephone cable has four wires that look like they maybe 16 or 18 gauge. Forty feet is my guesstimate at the moment, it could be a longer distance.
Since I am not an electrical engineer, I am not sure how I would go about calculating for the voltage value requirements. Any help would be appreciated.
