COM Express
Standardized Computer-on-Module Platform
COM Express is an open standard that defines standardized form factors and pinout layouts for Computer-on-Modules. Each module integrates the essential computing elements such as processor, memory and core I/O interfaces into a single board, while a separate carrier board handles application-specific connectivity and expansion.
Â
Portwell’s COM Express lineup spans Type 6, Type 7 and Type 10 modules, designed for industrial, embedded and edge computing applications.
COM Express Form Factors
Portwell’s COM Express lineup is available in three standardized form factors:
Mini: 84 × 55 mm
Compact:95 × 95 mm
Basic:125 × 95 mm

COM-HPC
Computer On Module – High-Performance Computing
Â
COM-HPC is a high-performance expansion card for servers. It uses the same concept as COM Express but increases the connectors from 440 pins to 800 pins to support more expansions and improves the speed of the I/O interface with PCIe Gen 4 or Gen 5 (32GT/s), USB 3.2 Gen 2×2 (20Gbps) or USB 4 (40Gbps), and 25G KR signals. COM-HPC has two module types: Server and Client.
COM-HPC Server: Provide superior computing performance and enhanced network throughput.
COM-HPC Client: Support comprehensive high-speed I/O interface.Â
COM-HPC is the perfect choice for server applications. It provides up to 65 PCIe and 8 KR Ethernet lanes, making it ideal for connecting servers and other devices. And it also features a CPU with a TDP of up to 150W, so you can get the performance you need.

Frequently Asked Questions
A COM Express module is a compact Computer-on-Module that integrates the processor, memory and core computing functions on a standardized board. A separate carrier board provides the application-specific I/O and connectivity.
COM Express modules are available in different pinout types to support varying I/O requirements. Portwell offers Type 6, Type 7 and Type 10 COM Express modules.
The COM Express specification defines different form factors. Portwell’s current lineup is available in Mini (84 × 55 mm), Compact (95 × 95 mm) and Basic (125 × 95 mm) form factors.
The COM Express module provides the core computing functions, while the carrier board provides application-specific interfaces, connectors and expansion. This modular approach allows OEMs to develop customized systems while using a standardized computing platform.
COM Express provides a flexible and scalable approach to embedded system design. OEMs can develop a customized carrier board for their application while retaining the option to select different COM Express modules based on processing, I/O and performance requirements.
