What Are Embedded Computers?
Embedded computers are complete computing platforms designed for integration into larger systems. The category includes single-board computers(SBCs), system-on-modules (SoMs), compute modules, and embedded processors running full operating systems (Linux, RTOS). They provide more processing power than microcontrollers, supporting applications like computer vision, edge AI, networking, and multimedia. LCSC stocks 2,000+ embedded computer SKUs.
Embedded Computers — Definition and Sub-Categories
An embedded computer is a specialized computer system designed to perform dedicated functions within a larger mechanical or electrical system. Unlike desktop PCs, embedded computers are optimized for specific tasks with constraints on power, size, cost, and real-time responsiveness.

How to Choose: Embedded Computers Selection Guide
Choose between SBC (quickest to prototype, all-in-one) and SoM (compact, requires custom carrier board for production). For Linux applications needing GPIO control, SBCs like Raspberry Pi alternatives are ideal. For edge AI and computer vision, choose platforms with GPU/NPU acceleration. For industrial applications requiring long-term availability, select industrial-grade modules with guaranteed 10+ year supply.

Frequently Asked Questions
Q: What is the difference between an SBC and a microcontroller dev board?
An SBC runs a full operating system (Linux, Android) with application-grade processing (multi-core ARM Cortex-A), multiple GB of RAM, and desktop-class connectivity. A microcontroller dev board runs bare-metal or RTOS firmware on a simpler processor (Cortex-M) with KB of RAM. Use SBCs for complex tasks (vision, networking, GUI); use MCU boards for simple control.
Q: What is a System-on-Module (SoM)?
A SoM packages the processor, RAM, flash storage, and power management onto a small module with edge connectors. You design a custom carrier board for your specific I/O needs. SoMs reduce time-to-market (no complex BGA routing) and allow module upgrades without redesigning the entire product.
Q: Can embedded computers run AI workloads?
Yes. Platforms with GPU or NPU (Neural Processing Unit) acceleration can run inference models locally. NVIDIA Jetson series is popular for computer vision. Some RISC-V and ARM platforms include dedicated AI accelerators for edge ML tasks.
Q: How do I choose between ARM and RISC-V embedded computers?
ARM has a mature ecosystem with extensive Linux/Android support, driver availability, and community resources. RISC-V is open-architecture with growing ecosystem but fewer off-the-shelf software options. Choose ARM for production projects requiring proven support; consider RISC-V for research, cost optimization, or vendor independence.
