Before we can start laying out a board, we’ll need to create a brand new footprint (aka 'package' in Eagle), schematic symbol, and device for it before we can begin to layout a PCB. In your PCB Library item (the one that is linked to your schematic symbol) use the Place -> Pad, select 'Multi-Layer' as Layer, enter a hole size (.7mm) and a pad size (e.g 1.5x1. The FT230X from FTDI looks like an interesting new IC. Don’t trust anyone or anyone’s library without a one-to-one print and a thorough review of the datasheet and pin mapping. Easy, Powerful, Modern The world’s most trusted PCB design system. Sometimes I’ll use a friend’s library, but we all make mistakes (I actually owe David Mellis a beer for messing up one of his boards because he relied on a footprint of ours). I have lost so much money on PCBs that had the wrong footprint that I don’t use the built-in libraries, Eagle or other. For example, Eagle may have a given footprint (SOIC-8 or QFN-24) but I wouldn’t trust it.
