 The protection circuitry for DATA, with the zener diode and PTC resistor, comes from the [[http://​ruggedcircuits.com/​html/​ruggeduino.html|Ruggeduino]],​ and makes it possible to withstand applying 12V to DATA indefinitely. More detailed explanation of how it works [[http://​forums.trossenrobotics.com/​showthread.php?​5675-USB2AX-v3.1&​p=53101#​post53101|here]]. This situation can easily happen in real life with a shoddy custom or damaged cable, and improper protection could result in a fried motherboard... ​ The protection circuitry for DATA, with the zener diode and PTC resistor, comes from the [[http://​ruggedcircuits.com/​html/​ruggeduino.html|Ruggeduino]],​ and makes it possible to withstand applying 12V to DATA indefinitely.
