Overview
Timer smd is an open-source printed circuit board by gipi, from the gipi/AVR-experiments repository on GitHub. It is a 2-layer board of 80.3 × 31.2 mm with 21 parts on 15 nets, routed with 5 tracks and 0 vias.
It is built around the ATMEGA328P-PU. Its parts include 6 resistors, 3 capacitors, 3 connectors, 3 switches and 1 IC. It belongs with the AVR (ATmega, ATtiny) boards of this library.
Main components
1README
READMEThis repository will contain projects AVR related.
Each project is contained in a directory of its own and in order to compile it you can
$ cd $ make upload
It's possible to install the dependencies using the following command in a Debian-like sistem
apt-get install gcc-avr binutils-avr avr-libc
In the libraries/ directory are contained some routines very useful to AVR projects. Are intended to be incluede in your source code and not linked since it's very likely that the F_CPU or MCU values are different from what you expect at compile time.
It's also possible to flash into Arduino this code (not all code will work)
using the PROGRAMMER variable:
$ make PROGRAMMER=arduinoif not indicated will use the buspirate. Obvioulsy the code must set the MCU
and F_CPU accordingly.

Questions
How big is the Timer smd PCB?
It measures 80.3 × 31.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Timer smd use?
21 parts, built around the ATMEGA328P-PU. 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 Timer smd KiCad files?
From the gipi/AVR-experiments repository on GitHub, at the commit this page was made from: the board is stuffs/Timer/kicad/timer-smd.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Timer smd design in my own project?
Its repository states no licence, so its author keeps all rights: ask gipi before reusing the design.
