I'm a beginner with electronics and I'm building my first solar powered robot. I now have a 50cm long (1.6 feet) small pipe through which I want to put four wires; 2 for the power from the solar panel, and two for I2C to read some sensors. I've got two 100W solar panels, but I doubt I will ever get more than about 120W through it.
I don't know if the size of the wires matter, but currently I'm using 22AWG for the power, and 30AWG for the I2C.
I had some trouble before when the wires from the ESC to the BLDC motor and the PWM wires to a servo where touching eachother. Before I build this part of the robot I now wonder whether I will get into trouble if this I2C and the power are cramped together in the small pipe.
Does anybody know whether this will cause trouble (interference or something)?
