If you did give or receive a Raspberry for Christmas, hopefully it was part of a kit where all the necessary parts are included. If not, you may be asking what you need to get started. First you will need a microSD card with your operating system of choice installed. Next, a USB supported keyboard and mouse, as well as a HDMI cable. If the monitor you intend to use does not support HDMI, then a proper adapter will be necessary. Finally, a micro USB power supply will be needed to power your new device.
