|Prototyping space on the m3pi expansion PCB.|
The unused areas of the m3pi expansion PCB have been configured for use as general-purpose prototyping space. The through-holes are connected in a breadboard-like pattern denoted on the top silkscreen by thick, white lines between holes. You can use this prototyping space to cleanly and easily add sensors or other custom circuits to your m3pi robot. The traces that connect the prototyping holes are all on the underside of the expansion PCB and can be selectively cut to modify the configuration of the prototyping space.
