DEPEPE 30 Pcs 40 Pin 2.54mm Male and Female Pin Headers for Arduino Prototype Shield

hello welcome to Wayne tech corner welcome to part one of building the breakout board for the eighteen mega 328p it's going to start off by creating a new project and we're going to work on building out the schematic for this board when we're done we should have a schematic that breaks out the analog to digital converters serial port a bunch of GPIO pins the i2c bus and also have an indicator LED so first thing we're gonna do is change the grid spacing to 2.5 4 millimeters and this will match the typical pin spacing and tip spacing for many of the symbols that people have created for the Eagle library we are going to make extensive use of the spark fund IC library that they've published you can find that on github or on the spark fund website and they've got a nice symbol here for the Dave mega 328p we're going to use the 28 pin P dip footprint since we're gonna be using all through-hol
