12v 1 Channel Relay Module Board

SKU: RE-002

12V 1 Channel Relay Module:  This Relay Board provides a single relay that can be controlled by any 12V digital output from your microcontroller.

Adopted SMD Optocoupler Isolation& jumper Set: The isolation circuit prevent damages to I / O port by relay switch current.The module has a jumper so you can set rather the unit state changes with high or low signal. Has screw terminals for relay (NC,C,NO) and for input; Coil +, coil – and trigger.

Wide Application: These relay board works well with ARM /PIC /AVR /MCU/Raspberry/CNC machine/ PS4 etc.

Humanization Design On Interfaces: All interfaces can be directly wired out through the terminals.Fault-tolerant design;fault-tolerant design,even if the control line is broken, the relay will not operate

Thank you for shopping at SharingWin — delivering smart electronics to your doorstep, wherever you are! 🌍

Hello, fellow geeks!

I’m an embedded systems engineer with a degree in IoT Engineering, and I’ve been deeply involved in AIoT product development for years. I’ve participated in several B2B projects from the ground up — covering open-source hardwaresystem architecturehardware selection, and solution implementation.

Through this journey, I’ve come across all kinds of AIoT products.
Some are smart, efficient, and elegantly designed; others are overcomplicated, packed with features that don’t solve real problems.
Over time, I’ve started focusing on one simple but important question:

Does this product truly solve the user’s core need?
Not just whether it’s ‘cool’ or uses the latest tech.

I firmly believe that great products don’t have to be complex or expensive — they just need to solve problems clearly and effectively, at a reasonable cost.

That’s why I created this site:
A space where engineers can connect, share, and learn from each other.

Here, I share great products and smart solutions I’ve encountered during projects — and try to explain why they’re good.
This isn’t about marketing. It’s about real experiencehonest judgment, and technical clarity.

This platform is called sharingwin, because I believe in shared success.

You’ll find high-value, practical tools and products here — to help you save time on selectionavoid unnecessary trial and error, and focus on what works.

As for me, I hope to use this space to connect with like-minded engineersexchange ideas, and — to be honest — maybe earn a little on the side too. That’s part of the fun. 😄

 

To all the makers and creators who’ve supported me along the way — thank you.
Due to some heavy personal projects recently, I haven’t been able to update or engage as frequently as I’d like — and for that, I apologize.
Moving forward, I’ll continue to optimize product content and be more active in sharing useful insights.

Your trust and support mean everything.
You’re the reason I believe this platform matters.

 

If you have any great products or ideas you think deserve more visibility, feel free to reach out.
I’m happy to help with sourcingconnect to the right supply chain, or feature it here so more engineers can see its value.

A single person has limited power —
but co-creation multiplies value.

If you believe in that too, let’s build something useful and meaningful — together.

  1. Module size: 50*26mm*18.5mm (L*W*H)
  2. Adopt SMD optocoupler isolation, strong driving ability and stable performance; trigger current 5mA;
  3. The working voltage of the module is 12V;
  4. The module can be set to trigger high or low by jumper;
  5. Fault-tolerant design, even if the control line is broken, the relay will not operate;
  6. Power indicator (green), relay status indicator (red)
  7. Humanized interface design, all interfaces can be directly connected to terminal leads, which is very convenient

Module Interface:
1.DC+: Positive power supply (VCC)
2.DC-: Negative power supply (GND)

Relay Output:
1.NO: relay normally open interface
2.COM: Common Interface Relay
3.NC: relay normally closed interface

High and Low Level Trigger Options:
It is low-level triggered when the jumper is connected to the low pin
It is HIGH triggered when the jumper is connected to the HIGH pin
