COM Express gets common implementation agreement

Three companies have agreed to support a common implementation strategy for COM Express modules and have produced a set of documentation describing how different products can be mixed and matched.

Adlink, Ampro and Congatec have agreed to support a common implementation strategy for COM Express modules and carrier boards.

The objective of this common documentation is to provide a platform whereby COM Express components can be freely and easy interchanged without the risk of technical differences between vendors.

COM Express is a well defined PICMG standard for Computer-On-Modules and offers great flexibility for many applications.

It defines two module sizes and five different pinout types.

The PICMG allows the implementation of COM Express products with some degree of freedom, ie in power sequencing, IO definition etc.

These choices are often a limitation for the interchangeability from one vendor to the other.

Some features simply don't work when using a third-party COM or carrier board.

The COM Express PnP implementation is documented in the form of a design guide that fully details the circuitry needed by system OEMs to achieve module interchangeability.

System companies need to create carrier boards that truly support multiple module vendors' products.

The design guide includes the implementation of all available COM Express interfaces.

All schematics for the carrier board are also provided.

This complete set of documentation is available at no cost for all interested parties at the comexpress-pnp.org website.

COM Express suppliers and system integrators supporting this PnP implementation are welcome to a free company listing at this website.

Additional module vendors and system integrators are welcome to join the COM Express Plug-and-Play Initiative.
