The TEWS QMC (VITA 93) module range delivers a modular, compact, and highly flexible platform for embedded I/O, communication, and signal processing in space-constrained systems. Designed to the VITA 93.0/QMC mezzanine standard, these mezzanine modules bring PCI Express connectivity and robust I/O capabilities to industrial, transportation, aerospace, defence, and test-and-measurement applications.
Each QMC module is a single-width, small form factor mezzanine that plugs into compatible carrier boards (e.g., PCIe or CompactPCI-Serial carriers) to extend system functionality without sacrificing size, power, or ruggedness. All modules are available in both air-cooled and conduction-cooled variants with extended temperature operation (typically –40 °C to +85 °C).
