Digi International, Inc. is an American Industrial Internet of Things (IIoT) technology company based in Hopkins, Minnesota.

History

The company was founded in 1985, and went public as Digi International in 1989. The company initially offered intelligent ISA/PCI boards (the 'DigiBoard') with multiple asynchronous serial interfaces for PCs. Today, multiport serial boards are still sold, but the company focuses on embedded and external network (wired and wireless) communications, scalable USB products, radio modems and embedded modules based on LTE (4G) communications platforms.

Patents

Digi International settled a patent infringement lawsuit with U.S. Ethernet Innovations LLC for $1.525 million in April 2013. In 2022, NimbeLink, a subsidiary of Airgain, filed a lawsuit alleging certain Digi products infringed on NimbeLink's Skywire cellular modems. The U.S. District Court for the District of Minnesota found all patent claims by Nimbelink to be invalid in May 2024.
