Under the trend of edge computing, in addition to the diversification of functional support and the improvement of computing power, the appearance and size of the system tend to be miniaturized. When the size of the system is reduced, the overall cost can be reduced. And the proper selection of SOM can lower the system power consumption. In order to achieve the benefits of system miniaturization and the convenience of quick module replacement, the choice of computing core will be the main key. Among them, OSM will be the best integration solution of many modules at present.

The computing core of an edge computer has many choices. The OSM module has better advantages than the others. Firstly, OSM is the smallest among choices of current standard modules, which can reach to 30x15mm. Secondly, the OSM module is soldered on the carrier instead of using an edge connector, which provides more stable system architecture. Finally, the function and performance are considered to FIT the environment when design with the OSM module, therefore, it can achieve low power consumption.
The module selected as the core of the computer is because of the convenience of replacement. At present, there are four commonly used modules in the industrial computer market: COM Express, Qseven, SMARC and OSM. The differences of above four modules depends on the size of the board, the way of connecting the backplane, the availability and quantity to support various interface. The largest is COM Express which can support the most complete functions. However, the size of the board can be as large as 125 x 95mm, which cannot meet the trend of miniaturization and mobility. As to Qseven and SMARC, although the size is like a business card, the assembly methods and interface distribution are gradually unable to meet the huge demand of large-scale edge computing as well as miniaturization. OSM satisfies both miniaturization and mobility at the same time, with 662 connection points under the largest area of 45x45mm, which fully meets the design requirements of industrial computers, whether it is RISC or CISC.
Edge computing has a wide range of applications, and it is used in different fields. Therefore, in the design of edge computing systems, different modules are often used with different baseboards, assembly methods, and functional interfaces to meet different transmission requirements and environmental tolerance.
The performance required by the edge computing system is to meet the needs of customers. It is stable, simple, easy to use, miniaturized and easy to maintain. Such an optimized system can reduce design complexity and development costs, also to achieve the goal of time-to-market.
