VNX+ Products

VNX+ is a new small-form-factor (SFF) VITA 90 proposed standard based on the published VITA 74 VNX standard. The VNX standard defines a form factor intended for spaces that are too small for a VPX module, at 89mm by 78mm with 19mm and 12mm height options. This form factor is roughly 30 percent of the volume compared to a typical 3U VPX. 

The VNX specification defines the physical size of the two standard-size modules, the module connectors, and the pin assignments of the signals on the module connector. The VNX+ standard expands on VNX introducing higher power capacities and new connectors.

COM Express Products

COM Express is a standard of multiple standards. Each COM Express Module COM integrates core CPU and memory functionality, the common I/O of a PC/AT, USB, audio, graphics, and Ethernet. All I/O signals are mapped to two high density, low profile connectors on the bottom side of the module. The COM modules plug into a baseboard that is typically customized to the application. 

The COM Express specification is hosted by PICMG.


PMC Products

PMC is a mezzanine standard operating on a PCI bus. WOLF is able to provide access to newer GPUs on PMC modules by utilizing a PCIe-to-PCI bridge and maxing out the PCI bus with PCIe x1 equivalent speeds.

The PMC standard is known as the IEEE P1386.1.


Custom Products

WOLF can also respond to requests for full custom designs, to meet a customer’s unique needs. All design inquiries are assessed and responded to with the delivery of a detailed functional specification within 3 business days. Full custom designs can be cost-effective for as few as 25 units.
