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.
