Case study: Challenges in incarnating a credit card sized SBC

Single Board 3.5inch, Console server, gaming platform

The initial goal in creating the Raspberry Pi credit card sized, Linux-based Single Board Computer (SBC) – targeted primarily at education – was to develop a response to the decline of students engaging with computer science and related engineering disciplines. Our desire was to reverse the trend of children becoming consumers rather than creators. The following case study follows the hardware development process from an early failure, initial prototypes, and through to the finished production design.

Over recent years there has been an increasing trend for children to be consumers of digital content rather than be future creators or engineers. This trend is driven by manufacturers looking to provide a seamless experience for target customers on a variety of electronic platforms, from gaming consoles to tablets and laptop computers.
As a result, access to raw I/O has become restricted. Similarly, any packaged provision of a programming environment is an anathema to the products’ commercial goals. The knowledge required to create “hello world” or flash an external LED has become simply too vast and the opportunity to learn vital skills such as structuring/codifying ideas and debugging has been largely subsumed by a click-and-shoot world. Any motivation to get under the hood and see how these products work is largely dissipated by the impenetrable barriers presented by these “locked down” systems.
The challenge in developing the Raspberry Pi credit card sized, Linux-based SBC was to break down these barriers and provide access at a sufficiently low cost so any fear of breaking the hardware was effectively removed. Having the hardware is only half the story; the provision of a rich set of programming environments such as Scratch and Python with libraries to allow control of peripheral hardware provides an engaging toolset for learning through experimentation and play in either the formal classroom or at the many school and independent maker (hackspace) clubs. The following case study shows how Raspberry Pi was developed from the ground up.

COM Express(tm) modules with AMD Embedded R-Series



A new starter kit for COM Express(tm) modules with AMD Embedded R-Series Accelerated Processing Unit (APU) is now available. The intelligent starter kit MSC C6-SK-A7-T6T2 contains a COM Express(tm) Type 6 baseboard, an active heat sink with fan and two DDR3 memory modules.

single board computer, networking appliance, gaming platform

The intelligent starter kit MSC C6-SK-A7-T6T2 contains a COM Express™ Type 6 baseboard, an active heat sink with fan and two DDR3 memory modules. Users of the kit are free to choose one of four COM Express™ Type 6 computer modules with Embedded R-Series APU from MSC’s MSC C6C-A7 product family. Furthermore, the starter kit is also offered with a 15 inch XGA TFT display with LED backlight. Different display types or touch screen panels are available on request.


The compact baseboard with dimensions of 140 mm x 184 mm offers the module socket and numerous important connectors, above all the newly available Type 6 interfaces defined in the COM Express™ specification V2.0. The interfaces include configurable Digital Display Interfaces (DDI) which can be used via three each DisplayPort and HDMI connectors and a DVI port. In addition, four USB 3.0 ports, Ethernet, VGA, HD audio, SATA and even a PCI Express™ x4 slot also found place onboard.................
