IPad Camera Connection Kit

The iPad Camera Connection Kit contains a set of adapters from Apple that allow a USB device or SD card to be attached to an iPad through the 30-pin dock connector. It includes an SD card adapter along with the iPod Camera Connector (which it superseded) for USB cameras and devices.

Usage
Plugging in a card or device through one of the adapters will open the iPhoto app (now Photos) to import images. Users discovered that they could plug in other USB devices through the USB adapter including flash drives, keyboards, MIDI adapters, and even PS/2 keyboard adapters.

History
The iPad Camera Connection Kit was first announced on January 27, 2010 to support the first iPad. It became available for pre-order on March 27, 2010 and began shipping in mid-April.

When the 30-pin dock connector was replaced by the Lightning connector, the kit was succeeded by the Lightning to USB Camera Adapter and the Lightning to SD Card Camera Reader.

Issues
iOS 4.2 reduces the power draw limit of USB devices from 100mA to 20mA, causing many unpowered devices, such as flash drives and keyboards, to become unusable through the adapter.
