STKa94xxCA set
The core of the STKa94xxCA set is the TQMa94xxLA module with a Quad Cortex®-A55 CPU. The components contained in the starter kit constitute a modularsystem enabling you to develop your own product ideas. Development of theEthernet interfaces, can be started immediately using the prepared combinationof the functionality unit of the starter kit that are matched to each other. Todevelop your own hardware you can use the certifi ed and qualifi ed circuitcomponents of the starter kit in your own designs.
