Hi guys!
I am picking a coil for LM2576 page 1.
I know I should pick a coil 20% over the maximum rating of "3A", but should it be SMD or not? Will an SMD coil work for my circuit?
I intend to send the signal from this microphone(PMOF-6027PN-42UQ) to the ADC pin of "nodeMCU v1.0, rev2", should I add an amplifier before that? The power supply for the microphone is "3.3V".
