What is a Pico-ITX Single Board Computer?
A Pico-ITX Single Board Computer (SBC) is a highly compact, fully integrated computing platform built on the Pico-ITX form factor, which measures just 100mm x 72mm. It is the smallest standardized motherboard specification, designed for ultra-space-constrained and power-efficient embedded applications. Unlike modular systems, an SBC integrates the CPU, memory, storage controllers, and I/O ports onto a single printed circuit board, offering a complete, ready-to-deploy solution for specialized computing tasks.
Key Specifications and Technical Details
Pico-ITX SBCs are engineered for low-power operation and reliability in demanding environments. They typically feature soldered, low-TDP processors from Intel or ARM architectures, such as Intel's Atom or Celeron series. Memory is often soldered as LPDDR4 or LPDDR5 for stability and space savings. Core specifications include:
-
Form Factor: 100mm x 72mm (3.94" x 2.83")
-
Processor: Low-power, fanless x86 or ARM CPUs.
-
Memory: Integrated, typically 4GB to 16GB of LPDDR4/5.
-
Storage: Support for eMMC or an M.2 slot for NVMe/SATA SSDs.
-
I/O: Includes multiple USB ports (2.0/3.2), HDMI/DisplayPort, Gigabit Ethernet, and GPIO headers for expansion.
-
Power: Operates on low-voltage DC input (often 12V), enabling fanless, silent operation.
Use Cases and Applications
The extreme miniaturization and rugged design of Pico-ITX SBCs make them ideal for embedded systems where space, power consumption, and reliability are critical.
-
Industrial Automation: As controllers for PLCs, HMIs, and robotic arms.
-
Digital Signage & Kiosks: Powering compact interactive displays and information terminals.
-
IoT Gateways: Aggregating and processing data from sensors in smart city and agricultural networks.
-
Medical Devices: Used in portable diagnostic equipment and monitoring systems.
-
Transportation: In-vehicle infotainment, telematics, and surveillance systems.
Comparison: Pico-ITX vs. Other Form Factors
| Feature | Pico-ITX (100x72mm) | Mini-ITX (170x170mm) | Standard SBC (e.g., Raspberry Pi) |
|---|---|---|---|
| Size | Smallest standardized form factor | Smallest for modular PCs | Varies, often non-standard |
| Integration | Fully integrated, soldered components | Modular (CPU, RAM, storage) | Fully integrated, SOC-based |
| Power & Cooling | Ultra-low TDP, strictly fanless | Low to mid TDP, may require fan | Very low TDP, passive cooling |
| Expansion | Limited, via headers and M.2 | Extensive (PCIe slot, SATA ports) | Limited, via GPIO and USB |
| Primary Use | Space-critical embedded systems | Compact desktop/workstation | Hobbyist, prototyping, light embedded |
Thinvent Solutions with Pico-ITX Technology
While Thinvent's product portfolio specializes in robust, fanless Mini PCs and Industrial PCs that share the core reliability principles of embedded SBCs, our engineering expertise aligns with the demands of Pico-ITX applications. Our systems, such as the Aero Mini PC series, utilize similarly efficient, low-power Intel processors (like the N100) in slightly larger, serviceable form factors. They offer the same fanless durability, wide operating temperature ranges, and flexible I/O crucial for industrial and commercial deployments. For projects requiring the absolute smallest footprint of a true Pico-ITX board, Thinvent can provide guidance and support for integrating these specialized components into custom solutions.
