Difference Between System on Module (SoM) and Computer on Module (CoM)
Historically, there have been distinctions between System on Modules (SoMs) and Computer on Modules (CoMs) with SoMs leaning towards compute engines like SOCs and ARM-based solutions, while CoMs were more oriented towards x86 architecture. However, in 2024, these terms are used interchangeably. The key components of both SoMs and CoMs include CPUs, GPUs, memory, flash, power, I/O, and they feature a connector that links them to the carrier card, forming the complete compute system.
Choosing Between SoM/CoM and Motherboard for Embedded Design
When deciding between System on Module (SoM), Computer on Module (CoM), or a motherboard for embedded design, the crucial factor is tailoring the choice to the specific needs of the system. It involves considering factors such as required functionality, compute power, necessary algorithms, software stack, and adhering to defined standards. The choice between SoM/CoM and other solutions like single-board computers or traditional desktop styles depends on the identified use case and the level of scalability or flexibility required for the application.
Are SOMs and COMs the same thing? Some people would say yes, but in reality, they are not. So, what’s the difference. To get a better understanding of the matter, I spoke to Matthew Burns, a Global Director at Samtec on this week’s Embedded Executives podcast. The second part of this discussion is which is appropriate for your application. Tune in to find out.
