Modular electronic prototyping platforms

A device, comprising:

• an electrically insulative substrate having generally opposing first and second major surfaces and that includes an orientation feature that is visible on both of the first and second major surfaces;
• four mounting holes defined through the substrate between the first and second major surfaces in a rectangular pattern, at least one individual mounting hole bordered by an electrical conductor associated with data transmission, at least one other individual mounting hole bordered by an electrical conductor associated with electrical ground, and at least one further individual mounting hole bordered by an electrical conductor associated with electrical power;
• and,
• opposing edge connector tabs defined by the substrate and having three exposed electrically conductive contacts that are coupled to the data electrical conductor, the ground electrical conductor, and the power electrical conductor and insulated from one another.

A breadboard, comprising:

• an electrically insulative substrate defining multiple holes extending between first and second major surfaces, the holes spaced at a given pitch;
• first second and third buses positioned on the substrate and electrically insulated from one another;
• and,
• a set of first second and third electrical contacts positioned on the first major surface around each of the multiple holes with each first electrical contact electrically connected to the first bus, each second electrical contact connected to the second bus, and each third electrical contact connected to the third bus.
