Power cables which have other factors frequency of the signals voltages capacitance of the cables etc. The length of the cable is around 7m. How important is the squareness of the square waves cables have a capacitive effect the longer the cable the more capacitance the more rounded your square waves become. Longer cables can also act as antennas receiving radio waves which can introduce interference onto the gpio.

The program is just a matter of reading the gpio and sending commands according to state changes. 0 50 degrees c ambient a good quality 2 5a power supply can be used if downstream usb peripherals consume less than 500ma in total. There are a lot of factors affecting the maximum length of signal cables vs. Getting started with the raspberry pi set up your raspberry pi and explore what it can do.

The maximum distance of poe can transmit 100 meters from the switch or hub regardless of where the power is injected due to the ethernet cabling standards.
