Improved Performances for My SBC

Using this expansion, our team found that the optocoupler can provide excellent isolation for different components in single board computers. The installation process was straightforward, no issues with compatibility either. The trigger expansion helped us to achieve superior performances on our projects, highly recommend it. The only downside maybe is that it is not necessary for all projects. Computers enthusiasts shouldn't overlook this useful component that can greatly improve their SBC's…

Pros
  • Provides a safe and reliable way to connect microcontrollers or other low voltage devices to high voltage circuits.
Cons
  • Requires basic understanding of electronics and soldering skills to assemble.

Works well Computer Components

I built an Arduino based cocktail maker with drinking fountain pumps, so I needed relays to control the pumps. These work great. The only problem I had was when I was careless in testing and flooded the relay board with water and shorted it out and turned on the random pump. But a couple of paper towels and a hair dryer solved the problem and the board worked perfectly again. It wasn't their fault, it was certainly my fault, but it was great that the board was strong enough to withstand the…

Pros
  • 2 Channel 12V Relay Module, can be controlled by any 12V digital output on your microcontroller.
Cons
  • Not everything fits

No documentation available

Seems to work fine, but mostly I had to redesign the pinouts and functions of the board myself. Use it to control the current of other relays controlled by the BeagleBone Green.

Pros
  • VCC: Power Plus; GND: power supply negative; IN1/IN2: Relay control port.
Cons
  • Makes me nervous
