Free PCB Sunday: XC9500XL CPLD breakout

We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few PCBs from one of our past or future projects, or a related prototype. Our PCBs are made through Seeed Studio’s Fusion board service.

This week we’re giving away two XC9572XL CPLD breakout PCBs.  Ever get stuck choosing the right logic chip combination or voltage level translator? Give up the hunt and create your own custom logic chip. CPLDs can give you the logic you need, with the pinout you want, while saving board space and board revisions.

Don’t forget there’s free PCBs three times every week:

  • Free PCB Sunday. The classic. Every week, right here on the blog
  • Tweet-a-PCB Tuesday. Follow us and get boards in 144 characters or less
  • Facebook PCB Friday. Free PCBs while you wait for the weekend

You can get the XC9572XL development board for $15.

Are you interested in blogging with us? Drop us a line. This probably won’t be a paid position, but you get a back stage pass, free PCBs, and free projects. US and international bloggers are welcome.

NEW: pick your free PCB from the Dangerous Prototype free PCB drawer. The first few commenters will now receive a coupon code for 1 PCB with free shipping. You can choose this PCB, or another PCB if you prefer. The online shop gives you a choice of free PCBs, and you won’t need to enter your details every time you win.

Some stuff:

  • Yes, we’ll mail it anywhere in the world!
  • Be sure to use a real e-mail in the address field so we can contact you for shipping info.
  • Limit one PCB per address per month please.
  • Like everything else on this site, PCBs are offered without warranty.

We try to stagger free PCB Sunday posts so every time zone has a chance to participate, but the best way to see the post first is to subscribe to the RSS feed.

  1. I was just thinking about building one of these. I would love one please, it will save me a lot of trouble. :)

  2. I should hopefully (touch wood) have one of these already either on its way or in the next batch from a previous token, so I’m not commenting in the hope of getting one. Thanks by the way!

    Anyway, this seems as good a place to ask as any, but if it’s not too much trouble what are the rough dimensions of the push buttons you use on stuff like this? I managed to match up all the other parts, but am not 100% sure about that one.
