Hardware design files for Tit with Atmega328pb
Ever wanted to have two hardware Serial Ports, two SPI, two I2C and more PWM pins on the Arduino Pro Mini? Tit has all of this, and retains the same form factor. Tit uses Atmega328PB at its core.
Tit, is pin compatible with Arduino Pro Mini, the chip Atmega328pb is software compatible with Atmega328p. Hence all the existing code and libraries should work without any changes. Tit uses higher version of avr-gcc toolchain, we have bundled it up as a package along with additional libraries required to access the extra features. Check the setup section on installing support for the board in the Arduino IDE.

Questions
How big is the Tit PCB?
It measures 18.3 × 33.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tit use?
26 parts, built around the ATMEGA328PB-AU and MIC5205YM5. 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 Tit KiCad files?
From the ExploreEmbedded/Tit-Hardware repository on GitHub, at the commit this page was made from: the board is Tit.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tit design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
