A recent interview with a KiCad developer
prompted some reflection on KiCad and EDA (electronic design automation) tools
in general. Below are samples of several PCB (printed circuit board) designs,
created with KiCAD, and implemented as part of the SimpleIoT project in the
last couple months.
The KiCad library has many parts in it, and other
organizations, such as DigiKey, Seeed, SnapEDA, and Ultra Librarian are also
providing libraries. If a KiCad symbol/footprint for a part is not already
available, it is relatively easy to create new symbols and footprints as
needed.
