Dr DSP, I don't know the exact history of PMOD, but I believe it's something Digilent came up with to serve as a quick prototyping need. Here's the link on Digilent's site (http://www.digilentinc.com/Products/Catalog.cfm?NavPath=2,401&Cat=9) I believe this encompasses all of their PMODs. At Xilinx, we're also starting to incorporate more PMOD connectors on our base boards. The ZC702 has 3 of these. Avnet's ZedBoard has 5. And more of our analog partners are designing PMOD cards for their various products. For example, Maxim has a new listing of 15 PMODs that address a variety of applications and connectors.

Pmod seems to be a fairly universal interface now. I have seen it on a few different FPGA boards (the Lattice iCE40 board for example). As more expansion boards like this one are available I think you can quickly prototype a complete system. Anyone know if there is a complete listing of available (and planned) Pmod compatible boards?

I just placed my order and in about a week, I should have one of these in my hands. It might be a good way to check out both the FPGA embedded processor as well as a pmod accessory. It comes with sample web server code so I can work on accessing the robot brain through a browser or Android app.

Not the least that you already have the FPGA dev board shown in this picture...

That definitely looks work checking out. My upcoming robot design will need WiFi and this may be an easy (easy is a relative term) and fast route to get there. The only downside is that, according to their website, it comes with VHDL sample code, not Verilog. On the other hand, I suppose I should get familiar with both languages.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
