CPLD board build

The nice guys at DangerousPrototypes sent me a free PCB code with which I picked up a CoolRunner-II breakout board. Yesterday I build the board, so here is a small walk through:

Like I read many times from other free PCB code’s builders, the famous DP free PCB packaging. Simple and effective.

The inspection. I’m no specialist, but it looks good 😛

Taking some parts from a previous project, a button from a kind donor PCB and a few more ordered from elpro.

This is a hand soldering job, so many tools around. I’m using a liquid flux from Loctite expired in 07.

Here, the four more legged parts are already in place posing with my trustworthy solder wick.

And the power section is complete.


After the headers are in place. Got them straight by inserting them in a breadboard.

The finished board.

And the beauty shot.

That’s all for now. Checking all electrical connections and power up test comes next time.
