EasyDriver stepper motor driver V4.4
Each EasyDriver can drive up to about 750mA per phase of a bi-polar stepper motor. It defaults to 8 step microstepping mode.(So if your motor is 200 full steps per revolution, you would get 1600 steps/rev using EasyDriver.) It is a chopper microstepping driver based on the Allegro A3967 driver chip. For the complete specs of the design, read the A3967 datasheet. It has a variable max current from about 150mA/phase to 750mA/phase. It can take a maximum motor drive voltage of around 30V, and includes on-board 5V regulation, so only one supply is necessary. The best part - low cost. The parts cost is maybe $10, less if you make the board yourself.

Confused why you say the microstepping mode is permanently set to 8-step. The standard V4.4 board defaults to 8-step mode but this can be changed using pins MS1 or MS2. It appears the board allows access to MS1 & MS2 pins, so why do you say it is permaQuestion by: admin on 2018-12-18 02:38:54
Hello Maxim, thanks for purchasing DOS Quad. Very sorry that we don't have a English documentation for SYS1.52 APP1.03 at present, we will upload it as soon as we finish translating it in English. Before it, you could install a version of the APP for HAnswer by: admin on 2018-12-18 02:38:54

Hello Werner, glad to know that you are interested in DSO Quad. The current version of this product we are selling is HW2.7, for the firmware and application , you can refer to our wiki(Answer by: admin on 2018-12-18 02:38:54
I have tried the exact setup described on http://www.schmalzhaus.com/Eas..., using the code from example 2 - but the motor only turns in one direction.
Hi Mihai, sorry for the late reply, we will check it and confirm what is the issue. Before this, you could use Sys v. 1.51, App v. 2.52 first. Thanks for your feedback .
Since this easydriver is v4.4 and the picture shows pins ms1 and ms2 available, allowing the selection of microstepping resolution: Has your description of the item been updated from v3?
Hi,Dear.You can keep in touch with our custom service(firstname.lastname@example.org),he'll help you with purchase.
Would it not be nice to have a compatible stepper in this catalog?
The only stepper available as of now is a 5-pin stepper which is not compatible to this driver.
Hi Jason , very sorry that we can provide the documentation of what is the difference of app1.0 because we are not the designer and I have contact to the supplier , but they can't provide this to us .
