Zoom™ AM3517 EVM开发套件

Logic PD’s product-ready software and hardware platforms fast forward your product development while reducing risk and controlling costs. The Zoom AM3517 EVM Development Kit is a high-performance application development kit for evaluating the functionality of Texas Instruments’ Sitara AM3517 microprocessor and Logic PD’s System on Module (SOM).

Application development is performed right on the product-ready AM3517 SOM-M2 and software Board Support Packages (BSPs) included with the kit, which enables you to seamlessly transfer your application code and hardware into production. The included SOM provides easy evaluation of the AM3517 processor.

The AM3517 SOM-M2 is ideal for applications that require high-performance graphics, including applications that require OpenVG and OpenGLES1.1 2.0 acceleration. The AM3517 includes an SGX530 graphics accelerator and multiple communication ports including wireless 802.11 b/g/n and wired 10/100 Ethernet peripherals. For commercial signage, medical imaging, avionics, and industrial displays, the AM3517 SOM2 allows for powerful versatility, long-life, and greener products.

The Zoom AM3517 EVM Development Kit includes the AM3517 SOM-M2, baseboard, application board, accessories, and software required to immediately begin development work.
