  • CPU, Power Supply, and I/O units can be configured as redundant or non-redundant systems in transportation, automation, avionics, defense, and other markets
  • 1.4” horizontal pitch (7 HP) per unit supports mounting on walls, DIN rails or side-by-side in a 19” sub-rack
  • Modular, scalable architecture removes backplane for configurable, cost-effective low-, medium-, and high-volume production runs

WAKEFIELD, MA. PICMG, a leading consortium for the development of open embedded computing specifications, has ratified the ModBlox7 base specification. The first-of-its-kind specification addresses industry’s need for modular and interoperable embedded box PCs by defining a flexible mechanical architecture and “units” that fit a 1.4-inch horizontal pitch (7 HP) form factor.

The ModBlox7 architecture removes expensive components like backplanes and shelf controllers to enable the creation of price-competitive systems even at low volumes. Up to 12 of the 7 HP units can be interconnected and mounted on walls, DIN rails, or inserted in a 19” sub-rack.

“With ModBlox7, we combine the advantages of modular standards like CompactPCI and CompactPCI Serial with the demands we see from box PC customers like cost sensitivity, small form factor, and low weight,” explains Mathias Beer, CEO of Ci4Rail GmbH and member of the PICMG ModBlox7 working group. “By combining all of this in a PICMG specification, ModBlox7 addresses the design requirements of our clients and avoids vendor lock in.”

The Building Block Architecture of ModBlox7

A typical ModBlox7 system consists of Power Units, Processing Units, and PCIe or USB 2.0/3.0 Input and Output Units (IOUs), each of which measures 1.4” or 7 HP wide. Units can also be extended in 7HP increments to 14 HP, 21 HP, and so on and remain compatible with the specification.

Power Unit blocks convert external supply voltage into a 12V internal voltage and connect to Processing Units via terminal wire-to-board or board-to-board connectors. Processing Units support an overall thermal design power (TDP) of up to 150W and interface with IOUs over high-speed board-to-board connectors.

While a minimum ModBlox7 system consists of just one Processing Unit and one Power Unit, they can support as many as four PCI Express-based or eight USB-based IOUs. For high-availability or safety applications, ModBlox7 systems can also be configured with redundant Processing Units or Power Units. The maximum number of slots supported in any ModBlox7 is 12.

The ModBlox7 standard defines a direct board-to-board interconnect in a box format to realize cost-effective system solutions,” says Bernd Kleeberg, CEO and Head of Sales at EKF Elektronik GmbH and chair of the PICMG ModBlox7 working group. “Thanks to native support for redundancy, ModBlox7 is also recommended for high-availability solutions.”

PICMG 2023 in Review: Specs, Specs and More Specs

COM ExpressCOM-HPCJess IsquithMicroTCAMicroTCAOpen Standards

By Jessica Isquith, President, PICMG

The end of every calendar year provides an opportunity to reflect on our achievements and shortcomings. But as 2023 draws to a close, I’m nothing short of astonished with what our membership has accomplished.

Seven specifications have reached significant milestones this year alone:

  1. COM-HPC 1.2. The latest and most advanced COM on the market was upgraded (to a smaller size) with the release of the COM-HPC 1.2 spec revision. Dubbed COM-HPC “Mini”, the 95 mm x 60 mm platform loses a connector compared to its fellow COM-HPC form factors, but still delivers 400 pins for carrying high-speed signals from the processor module to carrier boards.
  2. COM Express 3.1. The established leader in the computer-on-module (COM) market upgraded interfaces to provide increased speed and bandwidth over the previous generation. This will keep the specification compatible with leading-edge processor technologies.
  3. MicroTCA R3.0. MicroTCA continues its 15-year evolution, as Revision 3.0 of the specification add 100 GbE and PCIe Gen 5 interfaces to cement the open platform in high-energy physics and scientific research, communications, and medical applications for years to come. MicroTCA is also a favorite of Quantum Computing startups, many of whom have already adopted the standard in their R&D efforts.
  4. ModBlox7. The first open standard Box PC, ModBlox7, is in its final review phase and expected to be ratified by Q1 2024. It’s modularity, flexibility, and scalability is poised to address the demands of today’s industrial and transportation use cases.
  5. IoT Specs. PICMG’s IoT specification efforts continue to expand as work with Redfish APIs was formally adopted by the DMTF. With continued effort and adoption, the IoT.x family of specifications will enable sensor-to-controller-and-beyond data transparency that will drive the need for and application of compute intelligence at the edge.
  6. CompactPCI Serial Extension. CompactPCI, one of the original PICMG specifications, lives on in the form of CompactPCI Serial. A specification extension adds PCI Express Gen 4, 100 GbE, and support for other modern serial signals. The upgraded performance will allow CompactPCI Serial Extensions to keep targeting industry and transportation platforms where it has been successful for decades.
  7. InterEdge. InterEdge defines a set of specifications for process and automation control for the rugged far edge. This effort is a collaboration between PICMG and OPAF of the OpenGroup and backed by leaders in the energy and industrial markets. It is scheduled for release in early Q1.

All these accomplishments set PICMG up for an exciting 2024, which also happens to be the consortiums 30th anniversary of developing open embedded computing standards. With multiple new specifications primed to enter the industry, we’re looking forward to keeping up the momentum we’ve built over the last calendar year thanks to the hard work and determination of our member companies.

In addition to thanking existing members for their consistent contributions, we invite non-member companies to become part of the specification development process by joining and participating in PICMG. Through collaboration, significant problems are being solved that are reshaping multiple industries with open, interoperable solutions that enable thousands of embedded solutions to reach the market in an efficient and timely fashion.
