Overview
Pixie328 is an open-source printed circuit board by UserHackable, from the UserHackable/Pixie328 repository on GitHub. It is a 2-layer board of 50.8 × 20.3 mm with 8 parts on 27 nets, routed with 65 tracks and 1 via.
Its parts include 1 capacitor, 1 resistor, 1 IC, 1 connector and 1 crystal. It belongs with the AVR (ATmega, ATtiny) boards of this library.
README
README.mdPixie 328
This is a very bare minimum breadboard Arduino board.
It uses a standard FTDI connector on one end to program the ATtiny85 Micro controller with, and has a ICSP header to burn the boot loader on the other end.
It also has a place for a ceramic frequency clock, and an optional reset pullup resistor.
The pull-up resistor is optional, as the internal pull-up will work, unless you expressly turn it off.
Bare minimum, and inspired by Dale Wheat's breadboard Arduino.

Questions
How big is the Pixie328 PCB?
It measures 50.8 × 20.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pixie328 use?
8 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Pixie328 KiCad files?
From the UserHackable/Pixie328 repository on GitHub, at the commit this page was made from: the board is KiCad/Pixie328/Pixie328.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pixie328 design in my own project?
Its repository states no licence, so its author keeps all rights: ask UserHackable before reusing the design.
