5V 2-Channel Relay Module With Optocoupler - For Arduino, PIC, ARM, DSP, AVR Projects - Low-Trigger GPIO Interface

Hey makers and tinkerers!

If you're deep into an Arduino, PIC, or Raspberry Pi project and need to switch higher power devices, this 2-channel relay module is exactly what you need.

It runs on 5V and features optocouplers, which means your sensitive microcontroller is protected from voltage spikes.

You can use it to control lights, motors, solenoids, or anything else that needs a solid on/off switch.

The inputs are low-trigger, making it super easy to interface with your board's GPIO pins.

It's a simple, unbranded module, but it does the job perfectly for countless DIY applications.

Whether you're automating your home or building a robot, grab this relay module to bridge the gap between your logic and the real world.
