DROK BLDC DC 5-36V Brushless Sensored Motor Control Board Motor Driver Regulator Monitor 350W High Power DC Motor Speed Controller Module with Heat Sink, Control Switch

X11A versus X11B is significant. "A" version has no provisions for Hall effect inputs from motor equipped with Hall sensors. My 3 phase motor had these sensor outputs but I left them unconnected, and the X11A board ran it without issues, minimal heat, and good low-RPM torque with modest 2 amp 12 volt supply. I ordered another board but received the X11B version. I hooked up the 5 hall output wires from the motor to the intuitively obvious connections on the board. Motor ran with distinct roughness and both motor and board generated significant heat, so I returned before anything got fried and sought out specifically a second backup X11A version which now works just like the first board. Also, the X11A board includes a reverse switch wired in but the X11B does not. I am not up to speed on Hall sensors, so if you are you might be able to get favorable performance from X11B, but I am quite happy so far just ignoring Hall provisions as the motor runs fine without. FYI the motor is the $17 one from All Electronics.

Received wrong controller and instructions didn’t match the delivered controller. Only 1 of the 3 controllers that I purchased worked out of the box. Also, the mosfets from the working controller keep blowing.

Seems like the right answer to control a 3 phase brushless DC motor, but it has some issues. First, the one page documentation showing how to wire it did not match the board itself. You'll need to remove the heatsink to see the labels of the pins and jumpers. One I figured this out and powered it up, it spun the motor for a few seconds then stopped. Not sure why. Turning the potentiometer to adjust signal input had sporadic effect. I sill have not had success with this yet.I sent an email to their support but have not heard back yet. Really hoping I can get this to work!

First, I must say that the defect rate is high. I ordered four, two were defective. Next, I ordered three, hoping to get two good ones and I did. These are pretty affordable and Amazon's return policy protects against defective items, so no loss. If you do buy these, do a continuity test on the pos/neg pins, because one of mine had a dangerous short. I would never run these off any battery system that doesn't have a BMS to protect against shorts. Next, as other reviews state, I received a different model than pictured. The plus of this is that they accept PWM input (which is easier to generate from Arduino than an analog potentiate value). I had to learn by trial and error that these controllers only allow full speed in one direction (test CW/CCW pin both ways). In the other direction, the motors will only spin slowly and will cut out if over half throttle is given, so definitely not useful as a true bi-directional speed controller. When running 350W hoverboard motors, these get brutally hot, so I'm curious how long they'll last, will probably need fans.

I received the incorrect board. Instead of the ZS-X11A I received the ZS-X11B which was not what I bought. Making the entire thing useless since I needed the speed pulse signal output.

I also received a board labelled "ZS-X11B", which doesn't match the item description or the included guide. The outputs to the motor appear the same, but I'll need to do some digging to determine how to actually hookup to the inputs before I can say whether or not this actually works.

Ordered 6, only 2 worked, the other 4 were defective out the box!

Unit without Hall effect sensor connections works but the torque is greatly reduced on BLDC motor. The hall effect sensor connections provided on similar units provide muuuccchhh more torque on Mini Smart Unicycle Scooter Motor
