The Q7S is the latest in the Xiphos Q-Card family of low-cost, embedded nodes for control, processing and interface applications, primarily for aerospace markets. Q-Cards combine a small form factor with broad networking, processing and I/O capabilities. The Q7S consists of a Q7 card, which is specially equipped with space-ready software and firmware, and rigorously tested. At the core of each Q7S is a hybrid environment of powerful CPUs and reprogrammable logic, providing consistent, reliable performance. The library of logic and software functions is augmented by onboard analog and digital I/O.

Xiphos also offers a range of ancillary services for Q-card customers including additional hardware and firmware development, software hybridization and Linux driver/API & application software development.
