An embedded computer is a dedicated system — with its own processor, memory, storage and I/O — that performs a specific function inside a larger device. Because it does one job, it can be compact and cost-efficient.
Both have to balance processing, I/O, reliability, size, power and heat. An industrial computer must also survive extreme temperatures, humidity, dust, vibration and shock — and keep running for years.
Embedded computers are usually smaller than desktops or laptops. They range from microcontrollers in wearables to palm-sized single board computers, stackable PC/104 modules, fanless industrial PCs and HMI panel PCs. See the main types of embedded platforms.
Commercial off-the-shelf systems built on open standards let OEMs, ODMs and integrators skip developing custom computing hardware — reaching market faster and at lower cost on a proven platform.
Standards cover rugged components, software support, fanless thermal design, form factors (PC/104, EPIC, EBX, COM Express, Pico-ITX and more), security such as TPM 2.0, and environmental operating conditions.
Industrial automation, edge computing, data acquisition, remote monitoring and similar uses where reliability is critical and maintenance access is limited. Many models support continuous operation from -40°C to +85°C.
