DC Motor Speed Controller with Remote Control 12V 24V PWM stepless Speed Control Switch 10A Wireless Speed Controller Linear Actuator Motor Forward and Reverse Rotation

The media could not be loaded. I love this controller. Normally with DC pulse-width-modulated speed controllers, you can smoothly control the voltage; but those don't have a remote control, and this one does! As you can see in the video, it clicks through to several voltages with my 12 VDC power supply.When you press the Reverse button, you hear a relay click and the motor reverses almost right away. (I suppose you don't want to slam most motors with an instant polarity switch anyway.)The loud beep allowed me to walk all over the house with the remote's antenna extended, trying to go far enough where it would stop working. I got about 100 feet away and it was still responding to the remote's buttons.Ah yes, that beep - it IS loud, but I may either tape over the piezoelectric device to make it quieter, or I may desolder it from the board. But you may want a feature like that, so it's up to you whether that's a "plus" or a "minus"!

The media could not be loaded. I need to say up from that if we ignore the crazy RF interference this remote is generating, and if we ignore the issue of the headache-inducing ultra loud beeps this unit makes upon powering on and on every button press (apparently it thinks there's a contest between it and the smoke detector)... And then there's the issue with it semi-breaking (the speed is no longer variable.. It's always full on or off, and frankly that's probably because I severely overloaded it with some serious amps way over spec..)If we let this stuff slide...I like it. I was testing it with a 12V linear actuator (this is where the reverse polarity button is critical) and with some DC motors, on 12 and 24V inputs, and it worked as I'd expect for the price.Note: I do not think it's reasonable to expect this inexpensive prototyping device to do any more than it does. At least one reviewer didn't like the fact that it didn't "remember" the last power setting it was on before power cycling, and that it always starts on power level 5 of 6 (yes there are 6 power levels not including "off" despite the incorrect documentation on the product listing which says 5).I've made similar devices which "remember" the last settings, but to do that requires a form of NVRAM (on board, on the microcontroller, or even a microSD card, etc.) and of course that bumps up the cost. This thing uses a tiny 14SOP 8-bit control chip that only had something like 40 instructions total. It is for super-simple control logic and keeps the cost *and* standby power consumption way down. The device I made used a 32bit dual core espressif MCU with on board WIFI wired to relays, a dual MOS power controller, and I wrote a cross platform GUI controller app for Android/iOS/mac/windows/Linux that used mDNS/Bonjour to auto discover the device on my wifi network and auto-connect. Even without a dedicated RF remote, it would cost waaay more than this (factor in the human engineering and QA costs for the mobile apps, too, and don't forget ongoing maintenance and support costs).This device is not that. It's not a consumer end product. It's for prototyping and hobbyist use. And it's not something you'd design into any consumer project as-is, either. I mean, with that RF interference, good luck with FCC filing =). It's here to get you started, to save you time and effort so you can try things out.As a professional software and hardware engineer who worked for big names on consumer and pro electronics and software for 20 years before retiring early on a nice IPO, I *LOVE* prefab plug and play prototyping hardware like this. It has a purpose, and it's not to be the device you actually use outside of R&D or on a little hobby project.Anyway, I wanted to make it clear that it serves it's purpose very well.OH, and that annoying sonic beeper? It takes all of 10 seconds to remove (since you always have a soldering iron up to temp all the time... If not maybe a minute lol).

used it for display for art showdid what i needed it toogreat price

This has several flaws that are not good. There is no way to start the motor on a low speed. It forces you to start at max every time. It has 6 speeds, and takes about a second for each of those speeds to take effect, so it will take almost 6 seconds to get the motor down to low speed after turning it on. When you turn it off, and back on, it goes back to max speed. Ironically, it does remember what direction you were going at last. If you turn it on, switch to reverse, turn it off, then turn it on again, it will start in reverse. It seems odd that they made the direction persistent, but not the speed. I can think of several examples where persistent direction would be a bad thing, but zero examples of how persistent speed would be a bad thing. I just think the programming/design of this was not well thought out. Also, the beeper is super loud, and it beeps with each button press. I just peeled the stick off it and drove a screw into the speaker to silence it. Honestly, I'm have a hard time thinking of any application where this would be good. For a garage door, it would ram it full speed up, when it is already up, and full speed down when already down, so it's a no-go there. Ditto for motorized awnings and anything else with limits to the motion. The one and only application that might work is a fan.

Have not been able to get it to work yet But have not had the time to troubleshoot it. I bought this same model befor and it worked great which is why I bought another. I’ll updat this review after I can tinker with it some more. Based on my experience with the earlier model that I’ve purchased, I would still say this is a good product, I may have just got one that happened to be DOA.

This is one of those things that you oughta have on the bench if you enjoy tinkering with electrical playthings! A million ways to implement it-

I ordered this for my son because he likes to build things and he said he wanted one. He said it has worked great for his projects so far!

I set it up to run a motor from a 12v battery and it worked pretty good for a while. The first time I used it for over a minute the magic smoke came out. I may look into what failed and try replacing & adding a heatsink, but that project is off in the future. It says 10A, I would have expected it to hold up better.
