With the PCB fully operational it is now time to disassemble the breadboard prototype for the next project.
It has been a great little workhorse.
If you look carefully, you will see that the breadboard prototype uses the PMod connector and the PCB version doesn't.
This is because the signals on the PMod connector are also connected to other "Arduino" compatible pins (plus the fact that the connector is perpendicular to the other pins.
The photo provides a good comparison of the development of a product from initial concept to initial prototype.
