ACCES I/O 
ACCES is now offering the OEM market specialized USB boards for quick and easy I/O integration in both new and existing systems. USB is by far the most popular and compatible standard data interface for direct PC connection. Add the features you need in your application in hours, not days. Choose from over 100 different models and options (including extended temperature) encompassing analog I/O, digital I/O, counter/timer, and serial I/O configurations. If you don't see what you need, ask us and we will make it for you.
Our USB OEM product line features two different size form factors - USB/104 and USB/PICO. The USB/104 product line PCB size measures just 90mm x 96mm and the mounting holes match the PC/104 form factor for quick and easy installation in both new and existing PC/104-based systems. Our USB/PICO line was created for our customers which demand an even smaller footprint and certain specific I/O configurations. The size of these modules is exactly half that of PC/104 (72mm x 60mm) and can be mounted on Pico-ITXe next generation embedded CPUs.
Both USB/104 and USB/PICO are stackable or unstackable, making them one of the most versatile I/O form factors currently available. These boards are excellent for easy installation into OEM equipment and eliminate the labor required with traditional plug-in boards. Our USB OEM products are hot-swapable for quick connect or disconnect in mobile or stationary systems and all products features high-retention USB connectors manufactured for industrial environments.
