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. Please note: The Nexys A7-50T variant was discontinued and is no longer available for purchase.
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.
The Nexys A7-100T features the XC7A100T-1CSG324C.
The Nexys A7 is supported by Xilinx's Vivado Design Suite, along with the free WebPACK edition, which helps keep costs down for students.
