A system on module on Element (SoM) is just a lightweight, ready-to-use board that integrates all of the core the different parts of something about the same module. That usually contains the processor, storage, energy management units, and occasionally additional peripherals like Wi-Fi or Ethernet. Unlike a traditional single-board computer, an SoM does not include connectors and program ports pre-installed, indicating it must certanly be along with a service board to form a complete system.
