I recently bought a MAX9814 microphone. However i cannot wire my MAX9814 to my Nodemcu and RPI.
I don't want to use a electronic breadboard, but i want to connect/wire it directly to the nodemcu or RPI.
Online search only gave me the following: https://cdn-shop.adafruit.com/datasheets/MAX9814.pdf and Wiring and Test | Adafruit AGC Electret Microphone Amplifier - MAX9814 | Adafruit Learning System.
These are not applicable to my situation, does any has already wired above together?

This sounds like you have bought a board with a microphone, because a MAX9814 is just a chip.

No you can't wire it to a Raspberry Pi because there is nowhere to plug it. That is the Pi does not have the interface components required to use it. The Nodemcu however does, you can wire it up to any analogue input.
To use a Pi you would have to buy a USB sound board and wire a jack plug.

Not that I am aware of, but it is just two wires, can you not do that?
What exactly is that board, I don't recognise it. It has a gain pin on it and I suspect that has to be connected to something but without seeing the schematic of it I can't say what all its pins need to be connected to.

Cheers Grumpy_mike.
Do you know which pins i need to connect from the microphone to the nodemcu?
9814 - NodeMCU Pin Def (silkscreen)
Gnd to GND (G)
Vdd to 3V3 (3V)
Out to A0
AR and Gain may be left unconnected unless you have a good reason to do otherwise. "Gain" controls the maximum gain of the amplifer as per the silkscreen printing on the board. AR modifies the behavior of the automatic gain control but the default behavior is probably fine.
