2 Introduction
The SBCX board is designed to allow embedded application developers
to get up and running quickly on ave's SOMs, giving them a head start
on the total system design.
Fig. 1: SBCX
The SBCX platform presented here provides a compact solution for any
industry and can be easily interfaced with Plant Automation Control
thanks to IEC-61131 SW language environment and/or other plug-ins like
QT environment or multimedia GStreamer video applications.
This hardware proposal by AVE Embedded Systems is completed with
SW solutions (SoftPLC, QT, RTOS) which permit to reduce overall
system cost, and making SBCs ideally suited for deployment into a wide
range of cost-sensitive and robust industrial applications SBCX supports
a broad range of interface options dedicated to embedded applications,
including Fast Ethernet support, S card socket, LV S display, USB,
CAN, UARTs, GPIOs.
