complete the circuit topology. In this
manner, a variety of electronic systems
may be prototyped, from small circuits to
complete central processing units (CPUs).
However, due to large stray capacitance
(from 2-25pF per contact point), solderless
breadboards are limited to operating at
relatively low frequencies, usually less than
10 MHz, depending on the nature of the
circuit. The Figure 4-1 shows the outer and
insider structure of breadbaord.
