Adlink / Ampro Computers CM2-SXI-Q-74 PC/104 CPU Module

The Adlink/Ampro Computers CM2-SXI-Q-74 is a PC/104 form factor CPU module designed for embedded applications requiring a compact and rugged solution, offering reliable performance in harsh environments. This module integrates the functionality of a PC/AT motherboard and several expansion cards within a small footprint. It utilizes a 25 MHz 386SX-compatible CPU, making it suitable for cost-sensitive embedded systems that previously required custom designs. The CM2-SXI-Q-74 is engineered for embedded systems with a focus on compact design, low power consumption, +5V-only operation, a wide operating temperature range, and high reliability. It can be used as a standalone component on a proprietary application board or combined with other PC/104 compatible expansion products to create integrated control subsystems.
