#Toadstool-Mega328
Toadstool Development Board - ATmega328P
The Toadstool family is made up of breadboard-friendly prototyping boards that house a microcontroller, and modules called Caps that connect using a standard header. The prototyping board is analagous to an Arduino/Launchpad and the Cap analagous to a shield/boosterpack.
This repository contains the schematics for the Toadstool-Mega328 prototyping board, a breadboard-friendly PCB that houses the ATmega328P microcontroller (or other Atmel pin-compatible variants such as the ATmega8/48/88/168/328).
The boards were layed out using KiCad - KiCad is open source and awesome.
There are a number of other CrashBangProto respositories containing the schematics for other Toadstool boards and Caps, as well as sample code to get you up and running.
Visit the Toadstool Webpages for more information on the project.

Questions
How big is the Toadstool Mega328 PCB?
It measures 49.5 × 56.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Toadstool Mega328 use?
28 parts, built around the ATMEGA328P-PU and LD1117. 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 Toadstool Mega328 KiCad files?
From the CrashBangProto/Toadstool-Mega328 repository on GitHub, at the commit this page was made from: the board is Schematics/toadstool mega328.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Toadstool Mega328 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
