Micro/sys Releases StackableUSB™ Carrier Boards for Three Form Factors

Montrose, CA... A new suite of StackableUSB carrier boards just released by Micro/sys offers embedded system designers maximum flexibility to implement USB measurement and control systems. The Micro/sys USB4364, USB5364, and USB3364 carrier boards respectively support the Nano-ITX, Pico-ITX, and the 104™ Form Factors and provide OEMs direct connection from their processor boardís PC-style USB ports to StackableUSB Clients. The carrier board, utilizing the Nano-ITX, Pico-ITX, or the 104™ Form Factor mounting holes, attaches to the single board computer and creates up to four USB bays per carrier board. By simplifying the challenges of mating USB I/O devices to single board computers, Micro/sysí StackableUSB carrier boards afford users a simple solution for garnering more I/O flexibility and capacity on a variety of form factors.

"Embedded designers, who have seen the advantages of StackableUSB with USB, I2C and SPI, have been frustrated by not having an easy means to attach or interface the StackableUSB off-the-shelf control products into their systems. This release of three different form-factor-specific carrier boards provides designers easy access to the growing number of small, low-power, rugged StackableUSB I/O boards that are available. It makes it easy to customize any single board computer with just the right USB I/O that is needed for the OEM application," comments Susan Wooley, CEO of Micro/sys.

Depending on the application needs, the USB4364, USB5364, and USB3364 can be configured as a hub board or carrier board. As a hub board, each single USB port from the SBC can be expanded into 4 USB channels and operated off the hub carrier board. Alternatively, when just a carrier board, the USB4364, USB5364, and USB3364 allow an OEM to interface with up to four separate root USB ports from the SBC, assuming the SBC has that number of Client ports. Either way, each carrier board offers opportunities to attach StackableUSB peripherals easily and securely.

The basic USB3364 starts at $125 in single quantity. The basic USB4364 starts at $135 in single quantity. And the basic USB5364 starts at $135 in single quantity. Significant OEM discounts are available on all boards. Contact Technical Sales Dept., Micro/sys, Inc., 3730 Park Place, Montrose, CA 91020, phone (818) 244-4600, FAX (818) 244-4246, email:, URL:
