The Acer Iconia A510 is a tablet based on Android. I use the tablet as an intervalometer for time lapse photography connected to the DSLR-Camera.

The tablet supports USB OTG (USB On-The-Go). This means that other devices, such as a camera, can be connected to the device via USB. To connect a camera via USB you need a microUSB to USB adapter, the tablet has an microUSB connector.
