SBC-AM5728 For SOM-AM5728

summary:

Som-am572x is a small and powerful core board, which is based on Ti Sitara am572x series high performance chip design, through multi-core heterogeneous processing scheme, programmable multimedia processing and ultra high speed data communication interface.

Som-am572x core board can lead out the main resource signals of the chip, realize FPGA communication through GPMC bus interface, and support efficient high-speed data acquisition and processing. Due to its flexible interface and powerful performance, som-am572x core board is widely used in industrial automation control, human-machine interface (HMI), machine vision processing, intelligent transportation, VR / AR and other high-performance applications.

We have designed a mature baseboard bb-am5728 for som-am572x, which can be firmly combined through four 2 * 40pin board to board connectors. The baseboard supports commercial and industrial environmental applications, and has completed a series of certification. Once the debugging is completed, it can be directly put into use, which greatly shortens the development time and reduces the R & D cost for enterprises.
