Adafruit Industries is an open-source hardware company founded by Limor Fried in 2005.

The company designs and manufactures a number of electronics products, sells a wide variety of electronics components, tools, and accessories via its online storefront, and produces a number of learning resources, including written tutorials, introductory videos for beginners, and the longest running live video electronics show on the internet.

The name Adafruit comes from Fried's online moniker "ladyada", itself an homage to computer science pioneer Ada Lovelace. The company's goal is to get more people involved in technology, science and engineering. Project kits are designed to deliver practical systems—not simply academic exercises—and to encourage more women into the field.
