A compatible Vortext86DX3 3.5-inch solution for long life VDX-6326/27/28

June 14, 2022

A 3.5-inch single-board computer (SBC) is a complete computer that is ideal for space-constrained, compact applications that do not require too many expansions slot interfaces or peripheral functions.


The VDX3-6726 is a 3.5-inch solution with less power consumption, higher performance, and is cost-effective in replacing aging equivalents such as long life solution VDX-6326/27/28. It also provides backward compatibility to support older version of software, thus helping to extend the life cycle of existing products without extensive redesign.

Benefits of VDX3-6726 and VDX-6326RD-NF/VDX-6327RD/VDX-6328RD-NF

Even though the VDX3-6726 is the newer 3.5” SBC, the VDX-6326/27/28 still have its own features.


Vortex86DX3 Series 3.5” SBC:

The VDX3-6726 is powered by a 1GHz single-core (dual-core optional) Vortex86DX3 and 1-2Gb DDR3. This 3.5” (102 x 146mm) module is designed to replace aging AMD LX800 equivalents and requires less power consumption, higher performance, and is cost-effective.


Vortex86DX Series 3.5” SBC:


The VDX-6326RD-NF/VDX-6327RD/VDX-6328RD-NF have their own features, such as VDX-6326RD-NF has PC104 Connector, VDX-6327RD has 7 COM Port, or VDX-6328RD-NF has PC104+ Connector.
