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.
