QMC, VNX+, and More Modular Peripheral Expansion
What you'll learn:
- What is QMC VITA 93?
- Where and how are QMC modules used?
- How QMC works with VNX+ and CompactPCI Serial.
I talked with Tim Tews, General Manager at TEWS Technologies, about the company’s latest VITA 93 QMC offerings (Fig. 1). VITA 93 QMC is a new modular peripheral interface standard that leverages compact modules about the size of a long M.2 card. The modules are designed for rugged environments that need high-speed electronics. They can be convection- or conduction-cooled and work in industrial, commercial, military, and avionics applications.
QMC Carrier Boards for Modular Systems
Developers can design their own motherboards or carrier boards to support one or more QMC modules, or they can buy them. If opting for the latter route, TEWS offers a VNX carrier board that supports up to three x1 QMC modules, a single x2 module, a x2 and x1, or a single x3 QMC module (Fig. 2).
Tews Technologies provides other standard form factor carrier boards for systems such as CompactPCI Serial (Fig. 3).

I earned a Bachelor of Electrical Engineering at the Georgia Institute of Technology and a Masters in Computer Science from Rutgers University. I still do a bit of programming using everything from C and C++ to Rust and Ada/SPARK. I do a bit of PHP programming for Drupal websites. I have posted a few Drupal modules.
I still get a hand on software and electronic hardware. Some of this can be found on our Kit Close-Up video series. You can also see me on many of our TechXchange Talk videos. I am interested in a range of projects from robotics to artificial intelligence.
