Thanks so much for previous input.
Recall I want to drive this SSR from a digital out: Digikey 425-2403-5-ND The datasheet is here [https://media.digikey.com/pdf/Data%20Sheets/Sharp%20PDFs/S102,202S02.pdf]
What are the mechanics of getting current from a 12awg wire to this miniscule 0.8mm pin?
If I had a pcb I would use wire terminals and appropriate -width and -spaced traces. But if I am prototyping, it seems like typical jumpers would not be heavy enough? How does one make this connection in the prototype stage?
