Raspberry Pi -- popular for its $25 PC -- plans later this year to ship new hardware in the form of a smaller board that plugs into a custom motherboard slot, which could appeal to a new audience of makers, enthusiasts and enterprise users. The new computer has similar circuitry from the current Raspberry Pi design, which is an uncased board with key components on it. The smaller Raspberry Pi board can be plugged into SODIMM slots, which are typically found in small computers with custom motherboards. The new Pi will be more like a mini-computer inside a computer.
