What I want is a very small breadboard with pins at the edge that will allow it to sit on top of, and connect to, a regular breadboard. If I create the radio module part correctly, no wires will be needed to add it to the breadboard view. Just like a standard DIP package sits across the centre of a standard breadboard, this would sit on the new breadboard. And make connections to the underlying breadboard, which would then have the usual wires to the the Arduino. And in this case a 3.3volt regulator. The schematic view would (should) have the radio module with (rats nest) connections to the Arduino and voltage regulator. The breadboard wires and both breadboard parts, are just wires, and do not need a schematic representation. At least that is the goal.
Another way to look as this, is as a 'carrier'. A base DIP footprint that connects to a 2 row header.
I'm going to try again starting from a standard breadboard part, and also from a Header 1 part. Once I get a single connection to feed through properly, I can expand it to as many pins and connections as needed.
Maybe I can get a female breadboard pin to connect to another female breadboard pin. The initial failing attempt was putting a male pin at the end of the bus, to connect to the main breadboard.
