Need a simple way to switch mains-powered gear on and off from your Arduino or Raspberry Pi? The 4 Channel 5V Relay Board Module Relay Expansion Board For Arduino Raspberry is priced at Rs 149 on Tech Depot India, and you'll like how little fuss it takes to get four independent switches under your board's control.
What is the 4 Channel 5V Relay Board Module Relay Expansion Board For Arduino Raspberry?
Think of it simply: a relay is an electrically-controlled switch, and this board gives you four of them on one module, run off 5V logic, so your Arduino or Raspberry Pi can flip four separate circuits on or off. It's described as a "relay expansion board," which is a nice way of saying it's meant to add extra switching channels to a project that already has one or two.
You'll find it a handy building block whenever your project needs to control something bigger than the board itself can handle directly. Take a look at the full listing before you order so you know exactly what you're getting.
4 Channel 5V Relay Board Module Relay Expansion Board For Arduino Raspberry projects — what you can build
You'll probably reach for a 4-channel relay board like this for things such as:
- Home automation setups where you're switching lamps, fans, or small appliances
- Multi-zone irrigation or watering controllers
- DIY control panels that need a handful of independent on/off outputs
- Automating existing switches without rewiring the appliance itself
- Learning projects that introduce you to controlling higher-power devices safely
