Customer Comments

  • Are you sure this has 180 degrees rotation? From the datasheet, it sounds like only 45 degrees. Or dies “operating angle” mean something else?

    • This is actually something that appears to be oft-discussed in hobbby RC forums. Just as a summary: These are hobby devices with varying amounts of error (i.e. you’ll always want to send pulses and get the actual angles and compensate in code accordingly). The 45 degrees refers to a single direction. This implies that it has a 90° range if you take both directions. However, that’s is assumed to just be what the manufacturer is willing to state as being the range that they’ll ‘guarantee’; in practice many have found the range to be 180° .. or nearly that (e.g. 178°). And if that makes you think “ugh.. then how am I supposed to figure out what the actual range is?”, it looks like you could form a club with similarly frustrated people :) Your best bet seems to be to google the part and check people’s actual findings (keeping in mind that yours may vary somewhat).
