Tested. Works.

A project log for Ugly FPGA Breakout

Ugly prototyping with diminutive FPGAs...why not?

The PCBs arrived last night, but I had to wait for this morning for the box of parts from DigiKey - I almost got the timing right this time.  Here's the assembled board with a Roman denarius for scale.  It's pretty small.  The #TinyFPGA Programmer is plugged in on top.  It programs the FPGA just fine.

I was careful to apply just a little paste with a 25 Ga needle since I've been having issues with QFN packages. I still got 3 solder bridges I had to clean up with an iron, but otherwise it worked OK.  I think my paste is getting old - it's probably two years old now and never been in the fridge (I can hear you cringing, people :-)

I wrote some quick test verilog just to make sure all the pins work, and they do.

Now, I can build a few more of these things and put them to use.

I think I'm going to make a composite video frame grabber as a test.
