Dave Jones’ EEVBlog reviews $149 Digilent Basys 3 Eval Board based on Xilinx Artix-7 FPGA

Dave Jones frequently opens several packages on the Mailbag Monday editions of his EEVblog video blog. This week, he spends five minutes reviewing the $149 Digilent Basys 3 FPGA board based on a Xilinx Artix-7 XC7A35T FPGA. The review of the board starts seven minutes into the video and the review includes Dave’s short analysis of the board layout and some advice about placing bypass capacitors near an FPGA.

The Artix-7 XC7A35T FPGA has 33,280 logic cells, 1.8Mbits of block RAM, 90 DSP slices, and an on-chip multichannel ADC block. The Basys 3 board includes several peripheral devices useful for FPGA students and experimenters:


  • 16 user switches
  • 16 user LEDs
  • 5 user pushbuttons
  • 4-digit, 7-segment display
  • 4 Pmod connectors
  • 3 Standard 12-pin Pmod connectors
  • 1 dual purpose XADC signal/standard Pmod connector
  • 12-bit VGA output port
  • USB-UART Bridge
  • Serial Flash
  • Digilent USB-JTAG port for FPGA programming and communication
  • USB HID Host for mice, keyboards and memory sticks


The low-cost Digilent Basys 3 FPGA board represents a considerable step up from the company’s older Basys 2 board, which is based on a Xilinx Spartan-3E FPGA. The ARTIX-7 FPGA brings 15x more logic cells and 26x more RAM to the party and jumps the DSP capability from the Spartan-3E’s multipliers to the Xilinx 7 series DSP48E1 slices. In addition, you use the Xilinx Vivado Design Suite tools to develop designs based on the Artix-7 FPGA. One of the nicest things about the Digilent Basys 3 board is that Digilent has created one Web page with simple, clear instructions about how you get started with FPGA development based on Xilinx devices and design tools using the Basys 3 FPGA board.
