3.5” SBC powered by Vortex86DX3 SoC and runs on Linux, QNX, DOS and Win XP

Jun 28, 2022 — by Giorgio Mendoza 3,957 views

ICOP recently released a 3.5” Single Board Computer (SBC) that implements the 32-bit Vortex86DX3 System on Chip (SoC). The VDX3-6726 SBC was designed with comprehensive backwards compatibility to support older software and extend the life cycle of existing products without the need of complex redesign.

The VDX3-6726 is built around the single core Vortex86DX3 with a maximum processor frequency up to 1GHz and 1GB of DDR3 onboard. According to ICOP, this SBC was designed to replace mainly aging AMD LX800 equivalents and it consumes less power in comparison.

The display interface consists of one VGA port and a 24-bit LVDS LCD flat panel. VGA offers a maximum resolution of 1920×1080 @60Hz while the 24-bit LVDS supports a resolution up to 1024×768 @60Hz. 

For connectivity, there is support for one GbE LAN RJ45 port and two LAN ports via 4×2 pin headers.

The VDX3-6726 offers support for new and legacy I/O ports including a PS/2 connector for keyboard/mouse, four RS232/485 ports, four USB ports  (ver 2.0), one 26-pin parallel port, one PC/104 connector and one SATA connector for SATA DOM.

ICOP has specified that the VDX3-6726 runs seamlessly on older operating systems such as QNX, DOS, VxWorks, FreeBSD, Windows XP, Windows 7 and many more. In the past, the company has released similar SBCs that offer supports for legacy operating systems (i.e. VEX2-6415), although this model implements a faster processor and it has the option to upgrade the DRAM up to 2GB.
