SBC9261-I Single Board Computer
Embest SBC9261-I is a low power, high performance single board computer based on Atmel AT91SAM9261S ARM926EJ-S microcontroller intended for applications like HMI (Human Machine Interface), data acquisition system, handheld devices, and intelligent instruments. It has a flexible design with a tiny daughter board Mini9261-I mounted directly onto the mother board through a DIMM 200-pin connector.
The daughter board of the SBC9261-I has AT91SAM9261S processor and memories on board. It exposes most features of the AT91SAM9261S through DIMM 200-pin. The mother board integrates a rich set of peripherals and interfaces including Ethernet, USB Host & Device, CAN, RS232/TTL/RS422 Serial ports, Audio, LCD, Keyboard, SD/MMC, Buttons, LEDs and etc.
Embest offers Linux 2.6.24 BSP and WinCE6.0 BSP for this board. Customers can use it already or use it for your design reference. |
