Конструкция 8-ми битной приставки ,клона famicom. Максимально элементы применены для поверхностного монтажа . Печатная плата разработана для изготовления в домашних условиях ,поэтому для соединения дорожек на разных слоях использованы переходные отверстия ,для соединениями перемычками . в папке FAB/lut два файла svg с слоями верхним(уже от зеркаленным) и нижним
Плата размером 90х90 ,чтобы можно было потом распечатать на принтере EasyThreeD K9 , у которого печатающая поверхность 100х100,корпус.

Questions
How big is the Rev.1 f PCB?
It measures 90 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rev.1 f use?
131 parts, built around the LM358, MC34063AD, IS62C256AL-45ULI-TR and SS14. 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 Rev.1 f KiCad files?
From the cel366/dendy_clone_smd repository on GitHub, at the commit this page was made from: the board is rev.1_f/rev.1_f.kicad_pcb and its schematic rev.1/cpu_video.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rev.1 f design in my own project?
Its repository states no licence, so its author keeps all rights: ask cel366 before reusing the design.
