KRATKE UPUTE:
Isarani obli kvadrat koji se nalazi na nekoj rupi predstavlja da ta prikljucnica treba ici na uzemljenje:
Emiter od tranzistora,
Katoda od ispravljacke diode,
Katoda od LED zarulje,
Prikljucnica uzemljenja GND.
Isarani obli prvokutnik u donjem desnom uglu predstvalja dodatni, neobavezni prostor koji se moze koristiti za korekcie gresaka
Prikljucnice:
ConnA predstavlja konekciju ulaza a binarnog zbrajala
ConnB predstavlja konekciju ulaza b binarnog zbrajala
ConnC predstavlja konekciju ulaza c binarnog zbrajala ("Carry in", eng.)
ConnP predstavlja konekciju izlaza p binarnog zbrajala koji se koristi za kaskadiranje vise binarnih zbrajala ("Propagate", eng.)
ConnY predstavlja konekciju izlaza y binarnog zbrajala (Rezultat zbrajanja)
Conn5V predstavlja konekciju napajanja binarnog zbrajala (Idealno 5V)
ConnGND predstavlja konekciju uzemljenja binarnog zbrajala ("GND", eng.)
Varijacije plocice:
U kaskadi punih binarnih zbrajala, sve plocice u nizu osim zadnje, trebaju na mjestu komponente LED P napraviti kratki spoj, bilo vanjskom zicom ili tragom bakraParts

Questions
How big is the Full adder PCB?
It measures 125 × 65 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Full adder use?
60 parts, built around the BC547. 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 Full adder KiCad files?
From the IJPantic/Full_binary_adder repository on GitHub, at the commit this page was made from: the board is full_adder_kicad_files/full_adder.kicad_pcb and its schematic full_adder_kicad_files/full_adder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Full adder 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).
