ATmega 328PB Breakout board. This is inspired by/copied from/whatever-you-wanna-call-it from the One Square Inch of Goodness board by Jeremy Saglimbeni at www.thecustomgeek.com. I like his board very much but I wanted to add some bypass capacitors on the power rail, and then I remembered I had purchased some 328PB chips (the new ones that have slightly different capabilities). So I made a copy of his design, adding in the second I2C bus pins that would have gotten lost. I’m not sure if there’s Arduino support for this chip yet. Board and schematic in Eagle 7 format are on Github
BOM:
1 - ATmega 328PB TQFP
1 - 10k resistor (0603 size)
1 - 1k resistor (0603 size)
3 - 0.1uf capacitors (0603 size)
2 - 22pf capacitors (0603 size)
1 - LED (size should be obvious by now)
1 - 5x3 16MHz crystal
