Assigning new packages to Eagle PCB components

adafruit-eagle-component-creation-tut

If you've spent any time at all laying out your own circuit boards we're sure you've run into the issue of not having the right component or package available in the standard libraries. If it's a common part, chances are the symbol definition will be there.  But perhaps the footprint you want to use is missing? Here's an easy to follow tutorial which demonstrates how to assign new packages to … [Read more...]

Reverse engineering salvaged part footprints

So you just pulled a fancy component off of a board from some broken electronics and you want to use it in your own project. What if the data sheet you found for it doesn't include measurements for the footprint? Sure, you could pull out your digital calipers, but look at the measurements in the image above. How the heck are you supposed to accurately measure that? [Steve] found an easy answer for … [Read more...]

We love it when a PCB comes out right the first time. We're careful enough with our designs that if something is wrong it's usually a footprint problem, like we picked the wrong package for the components. Adafruit is helping to make the design process easier by sharing their Eagle library. Like the Eagle library version control we saw earlier in the month, this library is housed on github making … [Read more...]
