The USB Adapter PCB at the controller end\n  takes 24V from your power supply and USB from your Raspberry Pi and combines\n  them onto this cable. At the toolhead, the Nitehawk PCB splits them back out\n  to power the board and communicate with Klipper. The result is a dramatically\n  simpler toolhead wiring situation with no CAN setup required, no additional\n  software configuration, and a cable run that a builder with standard Voron\n  experience can manage immediately.\n\u003c\/p\u003e\n\n\u003ch3\u003eDrag Chain Rated — Use as Cable Chain or Umbilical\u003c\/h3\u003e\n\u003cp\u003e\n  The cable is engineered for \u003cstrong\u003econtinuous flex cycling\u003c\/strong\u003e in a drag\n  chain — the most mechanically demanding wiring environment in a CoreXY printer,\n  where the cable flexes and extends thousands of times per print session across\n  the full XY travel range. The \u003cstrong\u003e105°C nominal temperature rating\u003c\/strong\u003e\n  keeps the insulation stable in enclosed chambers. The same cable works equally\n  well in an umbilical configuration for builds where a drag chain isn't used.\n  The Nitehawk-36 version is \u003cstrong\u003efully over-molded\u003c\/strong\u003e at the connectors\n  for maximum strain relief. The Nitehawk-SB version is\n  \u003cstrong\u003epartially over-molded\u003c\/strong\u003e for a balance between strain relief and\n  routing flexibility.\n\u003c\/p\u003e\n\n\u003ch3\u003eConnectors — XT30 at Toolhead, Molex Microfit 3.0 at Adapter\u003c\/h3\u003e\n\u003cp\u003e\n  The Nitehawk end uses an \u003cstrong\u003eXT30 connector\u003c\/strong\u003e — a compact, high-current\n  rated connector that handles the 24V power delivery cleanly. The USB Adapter\n  end uses a \u003cstrong\u003eMolex Microfit 3.0 connector\u003c\/strong\u003e — a standard\n  precision connector that is field-crimpable and allows the cable to be\n  shortened if your specific build has less than 2 meters of cable run between\n  the adapter PCB and the toolhead. Cut and re-crimp at the Microfit end\n  only — do not modify the XT30 end.\n\u003c\/p\u003e\n\n\u003ch3\u003eCAN-Compatible Pinout\u003c\/h3\u003e\n\u003cp\u003e\n  Despite being designed for the Nitehawk's USB-based architecture, the cable's\n  electrical characteristics and pinout are also compatible with\n  \u003cstrong\u003eCAN bus toolboard applications\u003c\/strong\u003e. If you're building a custom\n  toolhead wiring solution on a CAN-based board that uses the same connector\n  standard, this cable can be adapted for that use case.\n\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLDO Motors\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible toolboards\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNitehawk-36 (NH36), Nitehawk-SB (NHSB)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTotal length\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2 meters (~2.15m actual)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSignal carried\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e24V DC power + USB data (combined single cable)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eToolhead connector\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eXT30\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAdapter end connector\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMolex Microfit 3.0\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCable rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDrag chain rated + umbilical compatible\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNominal temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e105°C\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated bend radius\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e28mm minimum\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOver-molding\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFull (NH36) \/ Partial (NHSB)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCAN compatible\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eYes — pinout supports CAN bus applications\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e✅\u003c\/td\u003e\n\u003ctd\u003e1× LDO Nitehawk umbilical cable — 2 meters, pre-terminated both ends\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhat's NOT Included\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e❌\u003c\/td\u003e\n\u003ctd\u003eNitehawk-36 or Nitehawk-SB PCB — sold separately\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e❌\u003c\/td\u003e\n\u003ctd\u003eUSB Adapter PCB — sold separately (included in full Nitehawk kits)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e❌\u003c\/td\u003e\n\u003ctd\u003eUSB Adapter Mount — sold separately\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhen Do You Need This?\u003c\/h3\u003e\n\u003cp\u003e\n  Order this if your Nitehawk umbilical cable has been damaged — a cut insulation\n  from a cable chain pinch, a strained connector from a crash, or a frayed section\n  from exceeding the rated bend radius.
