Comet A65 SOM Evaluation Kit

Evaluation and development kit using Comet A65 SOM:

The Comet A65 SOM Evaluation Kit is a kit designed to support the evaluation and development of the high-performance SOM "Comet A65 SOM" equipped with Altera® Agilex™ 5 SoC FPGA. It features 12GB of LPDDR4 memory, abundant I/O, and eMMC storage, making it suitable for industrial applications such as medical devices, robotics, and smart cities. The included carrier board features various connectors including SEAM8 and ADF6, and offers comprehensive management functions such as power and temperature monitoring and automatic fan control. Rapid prototyping is possible by utilizing both FPGA and HPS interfaces. Furthermore, a free license for Altera® Quartus® Pro Edition is included, allowing you to start development immediately.
