If you have holes in the PCB that would ordinarily need pin headers, you can temporarily populate them with spring-installed test point loops and appropriate clip-on probes. [1] If you have headers you need to connect to, pre-made breadboard jumper wires are available with female receptacles that do the job nicely. [2] I still prefer solid wire, stripped, cut to length and cleanly routed over a multicolored nest for actual breadboards, but for temporarily connecting pin headers it's hard to beat the pre-crimped connectors. 1. http://www.digikey.com/catalog/en/partgroup/color-coded-test-points/19725 http://www.digikey.com/catalog/en/partgroup/color-coded-test... 2. https://www.adafruit.com/products/266 https://www.adafruit.com/products/266
