From the project
Схема полного сумматора для изучения принципов работы алгебры логики в школе
Выполнено на транзисторах 2N2222 и резисторах по 1k и 10k. Схемы можно подключать последовательно. А так же, для удобства рекомендуется вывести элементы управления и индикации.
Разрабатывалось в EasyEDA, а после экспортировано в KiCAD

Calc: common questions
How big is the Calc PCB?
The Calc measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Calc?
71 components, from 11 distinct parts. The full bill of materials is listed on this page.
Where can I download the Calc design files?
From the makargon/calc repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Calc design in my own project?
The repository has no license, so all rights stay with makargon. Use it as a reference, and ask the author before reusing the design.
