8 of 11 — the interface names are Hiwonder's, but these positions are read off their render rather than a real board, and show dashed. Check them against the unit before relying on this.

Joints are numbered from the fingertip. 1 tip joint, 2 middle joint, 3 base joint on the palm edge, 4 knuckle inside the palm. The parts between them are lettered the same way: A tip segment, B middle segment, C base segment. So the middle joint of the ring finger is ring 2, and the part above it is ring B.

Servos 1 to 5 are the fingers, thumb through little. Servo 6 turns the base. Six leads were found in the wrong ports on this unit, so record what actually moves rather than what the port is labelled.

3 of 12 — positions are inferred from Hiwonder's render and show dashed. The docs say six joints — five fingers plus one pan-tilt — but the render shows a servo below the palm and another at the base. Confirm on the unit whether that is one joint or two.
