SBC 1926

SBC 1926 a perfect solution for industrial control and automation, provides lot of non-volatile storage options: you may connect a pen-drive to USB host interface. The USB host interface can be also used for connecting keyboard and mouse. The board runs Linux, so you may develop Linux based applications to access the on-board I/O as well as other high end peripherals like USB and Ethernet.

Specifications of SBC1926 board:
