Project Getting Started


I reviewed the completed research handoffs and checked the live schematic and PCB. This revision is still incomplete and remains on release hold—not an approved battery-powered design.
Completed
  • Preserved the pre-change backup.
  • Recorded your CNHL 3S battery requirements and researched battery monitoring, default-off protection, auxiliary supplies and a purchased motor converter.
  • Documented integration gaps and saved the verified continuation state in the revision handoff.
What remains unresolved
  • Motor power: no battery-protection or high-current motor-power circuit was added. The proposed TRACO converter is not selected or approved: exact-model capability and low-input thermal derating remain unconfirmed. FET/shunt sizing, fuse coordination, current limits, regeneration handling, harness losses and transient/thermal validation are unfinished. The 25–30 A option remains provisional capacity—not continuous demand—and D24V150F5 remains unsuitable for unrestricted 25–30 A service.
  • Face: still disabled. U4’s head-side supply remains unsourced, and EN remains pulled low.
  • C7/C8/C13: still generic capacitors without exact qualified MPNs; effective-capacitance/ESR qualification is unfinished.
  • Integration: firmware compatibility, audio tests, exact harness drawings and mechanical fit remain incomplete. The PCB is still the unapproved 160 × 100 mm placeholder.
  • Checks: the eight ERC categories returned by my inspection passed, but this was not a complete final sign-off. DRC still reports unrouted connections. No manufacturing files were released.
What I still need from you
  • Original/restored torso and head CAD, including mounting locations and cable-clearance requirements.
  • Photos of the received battery label and balance connector; installed harness lengths and cooling conditions.
  • Where not already supplied: exact head/display and Jetson-carrier revisions, plus the target firmware repository and commit. Joint duty/torque requirements are also needed if reduced-current operation is acceptable.
You do not need to resend the motor model or battery product identity. Execution stopped because your account ran out of ACUs.
