- In this lesson we learn how to use the module with FR120N , LR7843 and D4184 MOSFET to turn ON/OFF DC load up to up to 10A. HW-532 optically isolated from 5V to 30V load up to 10A depending on the module. Schematic shown, wiring diagram explained, different method of wiring with push button and potentiometer also shown.

Thank you! I wasn't sure how to wire it because it had only 2 terminals on one side and 3 on the other side, your video was the only help I could find!
Thank you very much for your lessons and codes.
Glad you like them!
Very Good
Thanks!
You are welcome. that's kind of you.
can you use an ESP32 to control the motors wirelessly with another ESP32?
👍
I wish you can do a review for XH-M411 STEP UP MODULE. THANK YOU
If they pay me to review it i will do it. Tell them to contact me via Robojax.com contact page
can it reverse the direction
Hi
I am trying to build a BOB BECK zapper
the zapper uses three 9 volts batteries in series.
a 100k pot is used to control he output .
Do you think I can use the mosfet module on your video ???
Can I use a ZK-PP2K driver instead of the Arduino to control the output ???
any tips ???
hi, thanks a lot for the video, very clear for newbies like me and easy to follow!. What i don't get is the need for the diodes. You say that "if you use a DC motor you need to add a diode". Why is that? is it true if you use a DC motor and a DC power supply? Also, in the rest of the video, i don't see you add the diode in your schematics.... Can you clarify a bit further? thanks!!
Same question. Maybe someone has an answer? :)
@@22chrs @Jean Gustang Baguette hm, i thought I had answered this morning...
The reason is that a DC motor is an inductive load. You can find a web with this and more information about this module if you Google it. I tried to post it a couple of times but my post gets deleted
@@22chrs google "flyback protection diode". When a DC motor turns off, it keeps spinning for a little bit, and now instead of taking voltage, it generates voltage. You don't want it to generate that voltage into your relay/arduino, so you need a diode to protect it.
Hey, can we use this on a 775 motor? I am building a PCB mill, and I can use it to control the speed of the spindle (775 motor) through the grbl shield.
suggestions are welcome from anyone!
hi, please what type of diode i need to use?
Hi, it depends on your load current. if your laod need 5A, then get 5A diode.
Hello, please tell me can we replace this with 5v relay module if yes then which is the correct module
Search my channel for they word motor or relay
will these work with common ground? like switching on/off lights in a car? thanx
it's a low side switch, which is to say it goes into the ground or negative wire of whatever you want to control. Like this "battery + -> bulb->mosfet-> -battery " . So it sits in the negative return from the bulb, not the positive from the battery to the bulb (thats a high side switch, you can get them as well) it has its own + wire connected to the battery as well to power it. If you put it into the common ground, interrupting it (between the common ground and the battery negative) then yes it will work, but everything will need to run through it that is also on that common ground, eg starter motor, unless you give that it's own non-common ground. I.E. the battery negative must only be connected to it, if there is another path to the battery negative from that common ground the electricity will just go that way and the mosfet will do nothing. You'd be better off taking whatever you wanted to control off the common ground, running their ground returns to the mosfet instead and then the mosfets neg would connect to the common ground.
@@m3chanist thank you. I already got it. I should have first looked onto the bottom side to realise that it has common + , not common ground. :) So it is not good for the car. thank you. But maybe you know similar mosfet board that has common ground that can be used in a car?
can this module used to dimming High power LED?
Yea it can.
how to make it work like trigger switch using button?
Did u watch the video? It is in the video
can i use it without external power?
You are using this module to control something. That thing needs power, connect that power to this module
Note:
Connecting 3x 1A diode is not advisable
Use 3 A diode or move on to higher amps.
Don't connect diodes in series or parallel.
this is command industry practice to connect diodes in parallel. There is no problem with that. and the same is true for series.
