Compact electret condenser microphone DEVKIT-ECM-001
Electret Condenser Microphones (ECMs) convert sound into electrical signals that contain a permanent electrical charge without the need for an external polarizing voltage. These models are available in compact packages as small as 3 mm in diameter and only 1 mm thick. These ECM microphones are comprehensive, offering omnidirectional, unidirectional, and noise-cancelling options, with higher sensitivity levels and signal-to-noise ratios for outstanding sound performance.
For easier prototyping and design testing, CUI also offers an ECM Microphone Development Kit consisting of four separate microphone evaluation circuits. (See below for more kit information)
