PUI Audio DMM Digital Microphone Evaluation Boards

PUI Audio DMM Digital Microphone Evaluation Boards are easy-to-use boards designed to evaluate DMM Digital Omni-Directional MEMS Microphones. The boards are designed to test specific microphones and the designated frequency per design needs. Solder pads with pre-punched through-holes make wiring to the evaluation board quick and easy. The microphones feature ±1dB tightly controlled sensitivity and wide frequency response. These microphones are designed for cloud-based applications and battery-powered designs. Each microphone comes with the option to configure for the left or right channel and is ideal for stereo applications. PUI Audio DMM Digital Microphone Evaluation Boards have the microphone attached for quick and easy testing.
