Topic: Pull 3.3V from Pro Mini regulator? (Read 1 time) previous topic - next topic


I'm wondering if I power the Arduino Pro Mini 3.3V with a raw voltage (9V, say) can the regulator power the Arduino and allow me to draw current to power an SD card socket from the Vcc pin? An SD card needs 50-100 mA at 3.3V. Anyone tried it?
Sometimes things are as they appear


I think you would be OK. I believe the regulator limit is 150ma so if don't have too much other loads it should work fine.
