I designed a -very simple- circuit powered by a 12V battery. I would like to add a sd card connector (its type is of no importance right now) on that circuit.
But I am concerned by the datasheets I find on the net:
- first. No operation voltage?
- second. How could I possibly feed a huge 250VAC RMS with my circuit?
- third. 100 VAC max is approx 70V DC (100 * 2sq2). Way too much as well.
- fourth. According to Ohm's law, I could put a 24 ohms resistor and be good.
I am pretty sure I miss something because one find those in every SoCs.
Could we make those fit my circuit anyway? (how?)
