Only suitable for motherboards with socket stepper driver installation.
0.9-inch OLED screen, the motor current and subdivision can be modified by buttons, and displayed on the OLED, the operation is simple and convenient; in the absence of OLED, you can use the serial port to connect to the computer, and use the serial communication protocol for parameter adjustment and query
S42C V1.0 Closed Loop Driver Control Board Specification：
Maximum speed: 2000RPM
Main control chip: STM32G031G8U6, 32-bit ARM Cortex-MO+, clocked at 64MHz
【ATTENTION】
1 、When inserting the adapter board, please pay attention to the direction of the adapter board. Notice the motor and the loop chain wiring sequence!
2、For the first time, the closed-loop driver board must be connected to the motherboard with firmware, and then the encoder shall be calibrated. The calibration time will take 1-2 minutes
3、Check if the driver is installed when connecting to the computer with the serial port.
4、When the data displayed on the display or serial port is abnormal, please remove the closed-loop driver board and check if the magnet on the motor shaft is in the center position. If not, please return it to the center for recalibration.
5 、After completing the calibration, do not set it immediately after power-on. Please wait for the initialization to complete (1-2s) before setting the parameters.
6、Please do not manually turn the motor after power on.
7、The distance between the magnet at the center of the motor shaft and the core encoder should be greater than 2mm.
8 、Full stability of machine structure must be guaranteed

I was making a robot that used a stepper, and this works beautifully for very fast and accurate control with an Arduino or something similar.Picture shown displays the pinout of an A4988 module, which the breakout included is meant to be a drop-in replacement for. This confused me a little bit, but all you have to do is hook up your motor's voltage source (like 24 volts in my case) to the pin labeled VM on the corner of the breakout. Connect the ground to GND, and make sure the same GND is also connected to the Arduino. Then, as shown in the image, there are pins on the other side named EN, STEP, and DIR. You want to connect EN to ground as well to enable everything, and use the STEP and DIR signals from your Arduino just like you were controlling any regular stepper motor with a driver. DIR signals what direction to be going, and STEP signals when steps should be taken.Make sure to look through the menu on the screen (it will turn on with just motor's power source on VM and GND), and change the step count, or direction, and make sure to calibrate it, etc.I hope this helps others looking to use this module for non-3D-printer tasks

Jumped into my Arduino project with the High Speed Closed Loop Driver Control Board and 42 Stepper Motor, and wow, it's been a smooth ride. This motor is quiet and packs a punch with great torque and speed, making my project feel like it's got a secret superpower.The built-in driver is a dream – quiet, smooth, and feels premium, not like some of the cheaper ones I've tinkered with before. It's nice not to have the constant whirring in the background. However, diving into something a bit more custom, like looping motor feedback to my Arduino, turned out to be a bit of a puzzle. The instructions weren't much help for non-3D printer tasks, leaving me to figure it out on my own. It seems doable, though, and I'm not giving up yet.Also, for those who might be wondering, the driver's microstepping starts at 2 steps, missing out on a full step mode. Not a deal-breaker, but worth mentioning.All in, this stepper motor and control board combo is a solid pick. It's been mostly good news for my projects, making them run smoothly and quietly. A little more guidance for us DIYers would make it perfect

This board came packaged well, but was missing the TCM2209 Driver chips that were listed to be included with the order. All I received was the main board and screen. I will be needing to either return it and play the lottery again, or just fork out the extra money for the driver chips on the side. Please correct this either with the listing title, or with the warehouse that is packing and shipping.

First with the bad, a 2 button interface is a little tricky to learn. Not a big deal and almost forgotten after the learning cure compiling marlin firmware (if needed). If you have an Ender 3 or clone expect the geometry to change on your machine. With this change you may be moving the y-axis limit switch and need a new limit switch mount. Plan on compiling your own firmware unless you already know why you don't have to.That aside, they were plug and play on my new SKR Pro 1.2 board. I spent the most time configuring options and recompiling and recompiling and recompiling....As write this I'm watching my first print on the new system. I have not tweaked anything for speed yet but it is flying and the 3dbenchy is looking great! If you understand how these printers work and want to up your game, I think these are worth a go.

Using with a highly modified ender3v2 to run a chimera 2x2 end and dual z. Using Marlin. has a template firmware.. and some instructions... has a few depreciated libraries in it.. dunno how those work.. i used marlin bugfix... gotta watch... this is not a "pro" the ~pin(dot)h files are not the same... if you pick the wrong one.. the temp control doesn't work, just does thermal runaway... its all over a few forums with people doing it...also some older documents had a few pins mislabeled... I am running the stock ender3 settings for now and i have successfully printed several dual material prints... more torque with better drivers.. should be able to hit higher speeds if i tried... auto cooling fan on/off.. case fan with auto on/off... optional multiple parts fans.. you can add whatever you can configure in the firmware.. configuring the hot end was the hardest part.. tip offset... addressing cooling fans... integrating new setup with slicer... without an SD card inserted the screen never sleeps... works well with octoprint...

Had been searching all over the sellers site for documentation on this controller board kit. Thought, well I'll just buy it, because I'm sure there will be documentation with the product. Nope! No pin-out diagram. Zero documentation, not even a link to documentation. What sad product support! Deciding whether to send it back now or torture myself trying to set it up blind.

This is my 3rd set of these motors/drivers. The first set was DOA out of the box and the second set died after a few days of use. The set I have now has been working flawlessly for a few months now. They are super quiet (they use the TMC2209 driver) , stay very cool even when ran for 20+ hours on a print, as well as having massive torque.My only con would be the bad QA. It seems these don’t get tested before they’re boxed and shipped. While the packaging and quality are top notch, the QA could use some work.

This little board overpass my expectations, Although it would be nice if the manual for use outside of 3D printing was a little more complete
