KNACRO Selector Switch Boxes Editorial Review

The KNACRO USB relay is based on the ATtiny45 chip and comes with a GUI app and CommandApp_USBRelay.exe enabling command prompt control. The product also works with Linux using the "usbrelay" command from the command line. The set up is easy and works straight out the box. It comes in 5V 2 and 4 port versions however, this product cannot be used in multiples on one system because the ID is the same so if you want to have different channels, you will have to buy a four-channel one. Additionally, it does not come with a USB cable and although the reviews are mixed most are positive with the open-source design being praised for its low cost.
