Initial sales are of the Model B, with plans to release the Model A in early 2013. Model A has one [[Universal Serial Bus|USB]] port and no [[Ethernet]] controller, and will cost less than the Model B with two USB ports and a 10/100 Ethernet controller.<ref name="SMSC-LAN9512-Website"/>

Though the Model A doesn't have an [[Modular connector#8P8C|RJ458P8C]] (RJ45) Ethernet port, it can connect to a network by using a user-supplied USB Ethernet or [[Wi-Fi]] adapter. There is in reality no difference between a {{nowrap|model A}} with an external Ethernet adapter and a {{nowrap|model B}} with one built in, because the Ethernet port of the {{nowrap|model B}} is actually a built-in USB Ethernet adapter. As is typical of modern computers, generic USB [[computer keyboard|keyboard]]s and [[mouse (computing)|mice]] are compatible with the Raspberry Pi.<ref name="VerifiedPeripheralList"/>

The Raspberry Pi does not come with a [[real-time clock]],<ref name="faq" /> so an OS must use a [[Network Time Protocol|network time server]], or ask the user for time information at boot time to get access to time and date for [[Timestamp|file time and date stamping]]. However, a real-time clock (such as the DS1307) with battery backup can be added via the [[I²C]] interface.
