SMARC

Compact form factor for energy-efficient embedded systems

SMARC (Smart Mobility ARChitecture) is a global standard for Computer-on-Modules (CoMs) that was developed specifically for extremely compact, energy-efficient embedded systems. It was first defined in 2011 by the Standardization Group for Embedded Technologies e.V. (SGET). Modules of this form factor are usually based on x86 SoCs or Arm® processors and are characterized by two defined sizes (82 x 50 mm or 82 x 80 mm). Thanks to a standardized 314-pin connector, SMARC modules enable simple and flexible connection to application-specific mainboards that accommodate additional functions such as audio, touch or WLAN. The modular approach ensures fast time-to-market, high upgradeability and future-proofing.

The SMARC specification defines the module dimensions, the placement of the mounting holes, the connector to the mainboard and the interfaces to be implemented, including the pin assignment.

The current pin assignment (314 pins) is defined in the SMARC specification 2.1.1:

Computer-on-Modules integrate the central functions of a bootable embedded computer, such as CPU, DRAM, boot flash, Ethernet and display transmitter on the module. The modules are used together with an application-specific mainboard, the size and shape of which can be defined by the customer. The mainboard carries the required interfaces and integrates additional functionalities if required, such as audio codecs, touch controllers, wireless communication interfaces, etc.
