NEED TO CLEAN UP LIBS, some are not used, and architecture is strange check component one by one and make agreement (e.g : there is 4pin_quartz in differents libs and the symbol don't even look the same)
and also COMPLETE SYMBOLS with datasheet, footprint, ...

Radioactivity: common questions
What microcontroller does the Radioactivity use?
The Radioactivity is built around the ATTINY1614, from the AVR/Arduino family.
How big is the Radioactivity PCB?
The Radioactivity measures 95 × 75 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Radioactivity?
40 components, from 24 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Radioactivity design files?
From the le-flav-b/VEMAR repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Radioactivity design in my own project?
The repository has no license, so all rights stay with le-flav-b. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Radioactivity without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
