If you use solderless prototype boards (solderless breadboards) for circuit testing, the USBmicro U401 (#CGU401) combined with a 30-pin header (#CGPINHEAD30) is a great way for you to connect a test circuit built on a solderless prototype board to your PC.
The one-tenth inch on center pin spacing of the U401 lends itself well to fit to a solderless prototype board that has the same contact spacing on its rows of pins:
All it takes is a little bit of soldering to attach the 30 pin header to the edge of the U401. From CircuitGizmos you can obtain both the U401 and the 30 pin header:
Soldered in place, the U401 will plug into the solderless prototype board from positions 1 to 30, as shown below:
Note in this picture that pin 7 of the U401 is +5V from the USB connection and that pin 9 is ground. I have made the connections from these pins to the power and ground bus of the prototype board. The LEDs in this picture are just hooked up to power and ground to light constantly.
Now PC control of circuits in a solderless prototype board is as easy as this!
