Electret Condenser Mic

Capture sound for your next electronics project with this standard Electret Condenser Microphone (ECM) capsule. These are pretty common little units, great for adding audio input capabilities. Ideal for sound detection circuits, simple voice interfaces, or audio recording experiments with microcontrollers like Arduino or Raspberry Pi. It requires a simple biasing circuit (usually a resistor and capacitor) to operate correctly. This 2-pin component is straightforward to integrate into breadboard or PCB projects. A reliable choice for hobbyists looking to explore audio sensing.
