Electret Condenser Microphone 9x7mm

This high-quality Electret Condenser Microphone features a 9x7mm through-hole (THT) design with large pins for easy PCB mounting and prototyping. The omnidirectional pickup pattern captures sound equally from all directions, making it ideal for voice recording, audio amplification circuits, sound-activated projects, and voice recognition applications. With excellent sensitivity and low noise characteristics, this microphone is perfect for Arduino projects, DIY electronics, intercom systems, and audio detection circuits.
