A device that allows connecting standard Universal Serial Bus (USB) peripherals to Apple’s iOS devices, like iPhones and iPads. For instance, one could utilize it to connect a MIDI keyboard to an iPad for music production or import photos from a digital camera to an iPhone directly.
These connectors extend the functionality of mobile devices, overcoming limitations imposed by the single port design characteristic of many iOS products. Historically, the need arose from users seeking to integrate legacy USB-based accessories with their Apple devices, boosting productivity and expanding creative possibilities.
