Daisy chain sample
The daisy chain sample features pins connected two by two.
in which the pins are connected to each other. This sample is used for testing continuity on
the board. The PCB needs to be designed the opposite way, so that pins that are
unconnected in the daisy chain sample are connected on the PCB. If you do this, by simply
connecting an ohmmeter between pin A1 and pin A3, the soldering process continuity can
be tested.
