Previous version of my FGPA dev board winners

(This was before I found out about the icoBoard with pluggable pmod accessories.)

How can I add networking to an FPGA development board?

Some development boards include a SoC that has an ARM processor and built-in networking. If you choose a plain FPGA board (e.g. Artix 7 or iCE40 UltraPlus), how can you add networking?

  • Ethernet-SPI/Bus Module ($24.95). Has a built-in chip with a TCP/IP stack, so it's much easier to get started.
  • ESP8266 WiFi Module ($5.56). Self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network.
