What magnetic encoder does MKS Servo42A have?

Hello! I am thinking to buy the MKS Servo42A however I couldn't find any information about the magnetic encoder they use. Does it have Allegro's A1333LLETR-T encoder as in MKS Servo42B or the better AS5047D?

Ok, so I got an answer directly from Makerbase. It turns out that both motors use Allegro's A1333LLETR-T magnetic encoder. In fact, previously they were using AD5047D but because the supply was very unstable they changed it to A1333LLETR-T.

They changed because it is cheaper. Do a search about this product and how dishonest these guys are, stealing others work !

Why are you saying that they are dishonest and how are they stilling other peoples work?
On their github repo they write:

Well, respect to Makerbase -- they managed to build a $20 closed loop stepper motor. They didn't steal anything, their product is open source and is based on another open source product (and they acknowledged the original creator).

They are breaking the license, ie they are stealing.

The firmware they are using is licensed as GPL V3 for non-commercial use.

Ie home users get to use it for whatever, but if you want to sell It you must get a commercial licence.

Open source like in: copy an open hardware design, use cheap (aka slave) labor and parts to sell it making an immediate profit (no development cost, marketing already done), steal open source firmware, change it a bit to put your logo for ex., then claim it is open source because indeed the original open source firmware can run on this cloned hardware !

OK, I reckon I bought a MKS SBASE to try a 32bit controler and Smothieware (original board hard to get where I live), Marlin without risking too much money. Got it to work without bothering the original creator BTW.
I recently moved to RRF.

I may toss it in the garbage can once a I settle for a firmware. No hard feeling as I learned something using it but I would NOT recommend it due to its limitation. Of course if you need support from Makerbase, forget it !

PS: I do paypal donation when I am happy and use "open source" stuff.
