System on Module
A complete .NET and C# embedded computing platform in a compact form factor. Each module integrates the processor, memory, and essential peripherals required to build commercial embedded products — drop it onto your carrier board and go.
When to choose System on Modules
Pick a SoM when
- You're going to volume production with a custom carrier board
- You want production-ready compute you don't have to design
- You need an industrial form factor (SMT or SO-DIMM)
- You want 10+ year supported computing in your product
Consider something else if
- You're learning the platform — Experimenter Kit
- You're evaluating for a commercial project — Development Board
- You're prototyping — Single Board Computer
- You need lowest cost at high volume — System on Chip
Designed for embedded product development
A system-on-module mounts onto a custom carrier board designed for the final product. The carrier provides connectors, sensors, power, and application-specific interfaces — the module brings the compute.
Common applications:
- Industrial automation systems
- IoT gateways and connected devices
- Smart kiosks and terminals
- Monitoring and control systems
- Custom embedded electronics

As many pins share peripherals, not all are available simultaneously. HDMI requires additional circuitry.
Some SBCs work as SoMs too
Castellated edge pads
Several SBC options have castellated holes — the same mounting style as the SMT SoMs. Worth considering when researching SoM options, especially for the SC13048 chipset.
