== Summary ==
The WP90 is a compact 180° servo motor with a digital comparator control system, metal gears, and 180° angular travel. It delivers up to 2.3 kg·cm stall torque at 6 V and suits small robots, remote-controlled models, pan-tilt systems, and cameras.

* Dimensions: 23.2 × 12.1 × 25.5 mm
* Weight: 13.0 ± 1 g
* Controlled via PWM pulse signal; digital comparator enables precise angular positioning
* Electronic protection: automatically outputs protective torque during stall
* No feedback system included

== Notes and version constraints ==
* The source lists no explicit control commands or protocol commands; only the presence of PWM control is described.
* Some values such as the no-load current at 4.8 V are unreadable in the source (“[email protected]”); “approx. 50 mA” was used as an estimate – please verify against the original document.
* Version-specific differences between hardware/firmware revisions are not documented; compatibility should be checked when replacing or updating.
* No certifications, warranty terms, or safety requirements are stated; these must be confirmed separately.
