MitySOM-1808ARM9 SoM


Systems requiring a general purpose embedded CPU computer on module board that can provide an array of hardware interfaces as well as rich user interfaces will find the MitySOM-1808 System on Module (SOM) to be a cost effective choice. The MitySOM-1808 features the Sitara AM1808 ARM based CPU from Texas Instruments. The MitySOM-1808 ARM9 system supports QNX, embedded Linux, Windows CE 6 and ThreadX operating systems.

An overview of the OMAP-L138 / Sitara AM1808 family of MityDSP modules can be found here.
