PC/104 Embedded PC Buyer's Guide

The PC/104 form factor remains a critical standard for rugged, stackable embedded computing, particularly in defense and aerospace sectors where SWaP (Size, Weight, and Power) optimization is paramount. While the industry is transitioning toward high-speed PCIe/104 architectures to support AI at the edge and modern sensors, the rebranding of the PC/104 Consortium to the RMS Consortium (Rugged, Modular, Stackable) in late 2025 signals a broader focus on modular ruggedization beyond just legacy form factors.

Key insights include:

Technical Shift: Adoption of PCIe/104 Type 2 for USB 3.0 and SATA support, replacing legacy parallel ISA/PCI buses.
Market Resilience: Strong demand in "New Space" (LEO satellites) and deep-sea exploration due to its vibration resistance and modular stackability.
Sourcing Dynamics: Availability spans from high-performance Intel Core i7 SBCs costing over $5,000 to legacy RS-232 I/O modules for system maintenance.

The attached report provides a detailed breakdown of these trends, technical specifications, and key market players.
