Overview
ATiny412-board is an open-source printed circuit board by GerardZ, from the GerardZ/AtTiny412_TrafficLights repository on GitHub. It is a 2-layer board with 31 parts on 21 nets, routed with 170 tracks and 10 vias.
It is built around the ATTINY412-SSN. Its parts include 18 diodes, 9 resistors, 2 connectors, 1 capacitor and 1 IC. It belongs with the AVR (ATmega, ATtiny) boards of this library.

So, what is this ?
Recently I bought a bunch of the new AtTiny412 series microcontroller, these controller have 8 pins, where 5 pins are useable by the user. They are programmed with the UPDI programming interface, occupying only one pin.
For a getting-to-know I quickly created this little project. It is a double trafficlight intended for a plain crossing.
The circuit is as simple as can be, 6 leds, 3 resistors, 1 capacitor, 1 attiny.
Techniques:
- Led multiplexing
- AtTiny412
Programmer:
I use a USB-C CH340 board, it is fitted with a 1k resistor seated between Rx and Tx, Rx is UPDI interface. IMPORANT: To get the thing going, I had to remove the leds fom the board. On hindsight, the Rx led would probably be sufficient but I removed all three of them (or there resistors)

Questions
What parts does the ATiny412-board use?
31 parts, built around the ATTINY412-SSN. 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 ATiny412-board KiCad files?
From the GerardZ/AtTiny412_TrafficLights repository on GitHub, at the commit this page was made from: the board is KiCad/ATiny412-board/ATiny412-board.kicad_pcb and its schematic KiCad/ATiny412-board/ATiny412-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ATiny412-board design in my own project?
Its repository states no licence, so its author keeps all rights: ask GerardZ before reusing the design.
