The Nexys A7 (previously known as the Nexys 4 DDR) is an incredibly accessible, yet powerful, FPGA development board. Designed around the Xilinx Artix®-7 FPGA family, the Nexys A7 is a ready-to-use digital circuit development platform that brings industry applications into the classroom environment.
Students can start learning right away with the Nexys A7 thanks to its versatile selection of interfaces, such as 10/100 Ethernet, USB, UART, JTAG, and VGA. With a built-in temperature sensor, microphone, and accelerometer, students can work on a variety of projects without needing any additional hardware. Of course, 5 Pmod ports are available for additional customizability and applications.
There are two variants of the Nexys A7: The Nexys A7-50T features the XC7A50T-1CSG324C, and the Nexys A7-100T features the larger XC7A100T-1CSG324C.
The Nexys A7 is supported by Xilinx's Vivado Design Suite. Both variants of the Nexys A7 are supported by the free WebPACK edition, which helps keep costs down for students.
