00:00Best Magnetic Encoders Under $500 Video Script
00:04If you've ever built a robot arm, a gimbal, or anything with a motor that needs to know exactly where
00:09it's pointing, you know the pain of angle measurement.
00:13Magnetic encoders fix that, and after digging through the top sellers, I found the best magnetic encoders under $500.
00:20Fair warning, every single one on this list costs less than $5, so the hard part is picking the right
00:26one.
00:27Let's go.
00:29Hashtag 1 MT6701 Magnetic Encoder Module, 14-bit, $4.35
00:36Kicking off the list is the MT6701, and it's the one I'd personally reach for.
00:41You get 14-bit resolution instead of the usual 12, which means noticeably smoother feedback and way better fine positioning,
00:48a big deal if you're running closed-loop control.
00:51It's I2C, it works over a wide voltage range, and it's advertised as a drop-in replacement for the AS5600,
00:58so code changes are minimal.
01:00At $4 and change, this is the accuracy for money sweet spot of the whole list.
01:05Hashtag 2 Tenster 2-Pack AS5600, $4.99
01:11Next up, this is the AS5600, and this listing has been my go-to for years.
01:1712-bit resolution gives you about 0.088 degrees of precision, which is more than enough for most hobby robotics
01:23and servo work.
01:25This listing specifically is a 2-pack, so for under $5 you get two modules, perfect if you're planning a
01:31multi-jointed arm and need an encoder on more than one axis.
01:35Rated 4.9 out of 5 with nearly 2,900 units sold, which tells you these are popular for a
01:41reason.
01:42Notes, all five listings are 4.9 lead with the MT6701's 14-bit resolution as the real differentiator, since price
01:50alone won't separate them.
01:51One honest caveat worth a line somewhere, these modules need a magnet and correct shaft alignment to work, and the
01:583.3V only listing may need level shifting for 5V boards.
02:02Mentioning that keeps the review credible instead of so easy.
