Walksnail Avatar HD Pro Camera (camera only)

Manufacturer page, USD 65. Camera-only upgrade part, powered from the paired Avatar VTX module over a 140 mm coaxial lead (no own voltage rail - voltage fields omitted). 1/1.8in Sony Starvis II, f/1.6, published 0.00001 lux -> night class while remaining daylight capable. 19x19x24 mm micro form. Camera-side draw not published; 1.5 W estimate, flagged. Gyroflow supported. voltage_min_v/voltage_max_v researched 2026-07-29. Caddx/Walksnail publish an input range of 6 V-25.2 V (up to 6S) for the Avatar HD Pro. size_classes declared 2026-08-03 as all five, not judged per class: this is a PILOTING camera (1.45-95 g across the whole in-slot set) and nothing recorded about it rules a size class out — a 14 mm nano body flies on an 18-inch airframe as readily as on a 5-inch. Weight is the one axis with real size relevance and it is governed PER DRONE by the composed thrust budget and the computed payload ceiling, never per class, so a size list is not where it belongs (Stephan, 2026-08-02: declare all five, narrow only on evidence). Flagged estimated because it is that default, not a measurement. Observation turrets in this category are NOT declared: the question does not apply to a payload item that never reaches the camera slot, and that exemption is computed from the same rule the slot scope uses rather than tagged here.
