AS5600 magnetic position encoder - best encoder for stepper motors

In this video I show you how to use the AS5600 magnetic position encoder. This is a very powerful chip for projects where you need a precise information about the position of a shaft. Therefore, it is extremely useful for stepper motor-related projects because you can use the sensor to directly measure the displacement of the shaft of the stepper motor. Its angular resolution is 0.08789°/bit, so if you use it with a stepper motor that has a 1.8° angular resolution, you can use the motor up to 3200 step/turn microstepping and still get decent numbers.

i have been banging my head against a wall for days and making no progress trying to figure this out through the GitHub for the AS5600 library as well as the Datasheet, but holy shit, this might be the most straightforward and easy to understand tutorial I've ever seen for anything. You are a god and the comments on your code are a thing of beauty.

I have literally never used an Arduino for anything more then turning on an LED before, let alone I2C protocol but I still understood this perfectly. it is messed up that you don't have more subscribers.

Great use of this idea in one of my projects. And the explanation of code is out of the world. Best explanation. 48 mins just went like that. Keep coming with more innovative ideas. Thanks!

Great video. Despite having worked in electronics and IT most of my life, I still learnt a lot from this presentation. Plenty of detail unlike some examples where buzz words and part numbers are thown out willy-nilly.

Excellent showing. There are a plethora of encoders out there, linear, rotary, absolute, incremental, optic, capacitive, inductive, magnetic, etc. so certainly is a good thing when someone can teach us and even cover the software. Also, this modules are pretty cheap to be easily adopted.

[jeanreinis]

You were right, I had printed the code I had the first time and compared it to the original one you have and it was different. I apologize for my oversight. I recopied the code and it compiled perfectly. Thank you.

Very good video.
AS5600 is a fantastic part. I have used this magnetic encoder for one of my project, and made high precision "potentiometers" with the size of the small rotary encoder 11x11x8mm high and absolutely crazy precision.

[davidemoschetta]

nothing really new but I liked the way you explained all, you gave me more confidence with this sensor.. thanks

Hello. Getting ready to learn about the AS5600 in conjunction with a 28BYJ-48 stepper, both of which I have already purchased. I found your video(s) extremely well presented and informative and consequently you have a new subscriber! 😀

I have the exact same AS5600 pcb as you and have scoured the ‘net high & low but cannot find a schematic for THAT exact pcb (which seems to be one of the most common ones using the AS5600 chip).

I’ve seen in other places on the ‘net other folks suggesting to make various mods (mostly removing components) for one reason or another but none have actually supplied a detailed schematic of that pcb.

What lead me to REALLY wanting that schematic was I saw in the Mfg.’s data sheet for the AS5600 chip (page 5, Fig. 13) that for 3.3 Volt Operation pins 1 & 2 (VDD5V & VDD3V3) get jumpered together and a (decoupling?) capacitor’s value is changed from 1µF to 10µF. For 5 Volt Operation, there is no jumper and the capacitor is left at 1µF. There are a couple of asterisked notes regarding the 3.3 Volt Operation and “OTP programming” (which I’ll be honest, I don’t know anything about).

I checked my AS5600 pcb's and there is a 0Ω resistor (jumper) installed between pins 1 & 2, however there are no visible markings on either C1 or C2 on any of the three AS5600 pcb’s that I bought, thus one of the reasons I’d like to see a schematic.

I see you’re powering your AS5600 pcb’s with 5 volts and clearly nothing’s exploding. Can you offer a simple explanation what this is all about?

Any chance you might have, or know (link please) where I might find, a schematic for that specific pcb?

Thanks, Rick

This video is awesome! Excellent explanation, great code and fully understandable to someone who's a amateur Arduino user.
I have a misalignment issue with my two X axis stepper motors on my DIY CNC router and this will be a perfect way to check their absolute position before and during milling.

Thank you for sharing your knowledge. I rarely comment, but this deserves praise!

P.S. Subscribed!

Thanks for the very clear video! Using coaxial cable for the DATA en CLOCK (I2C) works much better than regular jumper/hookup cable. If you have a lot of jitters, missing characters and unreliable measurements please give it a try. Just some cheap (thin) TV coax will do the work. Ground the shield wires to a metal part of your project. With this setup I have a reliable reading with a margin of 0.10 degrees with a minimal delay.

Дождался, лучшее видео-инструкция по этому модулю, огромное спасибо за труд и код. Проверил, всё работает.
I waited, the best video instruction for this module, many thanks for the work and code. I checked that everything works.

[kennyamat]

You don't know how long I've been looking for a tutorial such as this one. Thank you for your great tutorial

[cientistaanonimo]

I look forward to seeing more videos of you implementing the AS5600 magnetic position encoder in your projects, especially if you are a CNC milling machine.

[ArcAiN]

just a heads up, but you can further reduce that to 3 pins, as the circuit / chip also supports analog output using VCC, GND, and OUT.
While tinkering with them on a benchtop, 4 pins is fine, but when you're talking about implimenting these in real world environments, the reduction of even a single pin can be a huge savings in time, cost, and space.

For instance, in my situation, i'll be using these on a CNC machine for DRO positioning, and when you're talking 5 axis * 4 pins, those drag chains are going to pack up pretty fast.

[alfatech]

Very nice to see this.
BTW, there is a video on a similar type of encoder on Hackaday. Some of the people commenting there mentioned that the commercial versions are quite expensive.

[bulenttanriyakul]

This time we need a closed circuit stepper motor board for Nema 23 and Nema 34. But it is affordable. When you try to buy the boards in the market, it exceeds the price of ready closed loop step motors.

[ilenvantev]

Great video!The shaft is Stainless Steel, that is why it's non-magnetic.Some types of SS are, but I guess this one isn't.

[havehalkow]

It would be also interesting to see how one can read the angular position based on pwm and analog signals with this sensor)

[deakjozsef]

Dear, It is a wery good explanation. Thank you for a sharing.
Today I assembled everithing with Arduino Uno and I connected the Oled SDA-SDA, SCL-SCL and working well.

We can control and maintain the position of stepper motor using and encoder thank you I am subscriber to your channel
