I just created our first test jig utilizing the P75-LM3 pogo pins and a "real" PCB. It worked out very well, but it seems that the PCB hole sizing is pretty critical for the pins if you want a proper fit. Also, I'm somewhat concerned about the production barbarians damaging the pins.
I notice the website mentions receptacles for the pins. Can you give me a lead on a part number and where to purchase? Would Adafruit consider stocking the receptacles as well?
