1 Introduction
1.1 Pico-ITX Concept
The Pico-ITX form factor provides system designers and manufacturers with a standardized ultra compact platform for development. With a
footprint of 100 mm x 72 mm, this scalable platform promotes the design of highly integrated, energy efficient systems. Due to its small size,
the Pico-ITX form factor enables PC appliance designers not only to design attractive low cost devices but also allows them to explore a huge
variety of product development options - from compact space-saving designs to fully functional Information Station and Value PC systems.
This helps to reduce product design cycle and encourages rapid innovation in system design to meet the ever-changing needs of the market.
Additionally, the boards can be passively cooled, presenting opportunities for fanless designs. The Pico-ITX boards are equipped with various
interfaces such as PCI Express, USB, Ethernet, Displays and Audio.
1.2 conga-PA7
The conga-PA7 is a Single Board Computer (SBC) design based on the Pico-ITX specification. The conga-PA7 SBC features the Intel®Atom®
x6000E/RE Series and Intel®Pentium®and Celeron®J Series processors (formerly Elkhart Lake). With maximum 12 W TDP processors, the SBC
offers Ultra Low Power boards with high computing performance and outstanding graphics. Additionally, the SBC offers onboard LPDDR4x
memory, eMMC storage, multiple I/O interfaces, up to three independent display interfaces, and various congatec embedded features.
With small board size and low height keep-out zones, the conga-PA7 provides manufacturers and system designers with the opportunity to
design compact systems for space restricted areas.
The various features and capabilities offered by the conga-PA7 makes it ideal for the design of compact, energy efficient, performance-
oriented embedded systems.
