Product Features

• The module is a powerful, energy-saving, omnidirectional microphone with digital output and a lower port.
• The module has a high signal to noise ratio and is an excellent choice for near-field applications. The module features a flat broadband frequency response that results in a high resolution of natural sound.
• The I2S interface allows the module to be connected directly to digital processors such as DSPs and microcontrollers without the need for an audio codec for use in the system.
• The module is available in a thin surface mount case measuring 4.72 x 3.76 x 1mm. The style is lightweight, classic and easy to carry. Can be used as external microphone and speaker accessory for computers.
