The Kit
Printed Circuit Board
The Printed Circuit Board (PCB) is made of
resin and fiberglass, with a layer of copper on
the top and bottom. This is a 2 layer board, but
boards with more layers are common. We can
use PCB design software like the free KiCAD,
or Eagle, Altium etc to lay out our circuit. The
circuit is comprised of footprints that hold the
various components, and traces which are
copper connections between certain com-
ponents.
When the finished design is sent to the man-
ufacturer, they etch away the copper that isn’t
needed to form the circuit. The board is then
coated in a coloured layer that protects the
circuit. This is the mask. A different colour is
then applied. This is the silkscreen layer, which
is where the footprints, designations and oth-
er information are found. Short Circuit PCBs
have the traces drawn on this layer, to help you
follow the circuit.
Components
The kit comes with a variety of components.
They make the circuit function. Designing cir-
cuits can be incredibly complicated. Our kits
are designed to be simple to learn. They are
not always the most efficient or effective way
to design devices with these functions. They
are designed to teach various concepts that
can be applied in your own designs.
