Adafruit PDM Microphone Breakout

Adafruit PDM Microphone Breakout offers a fully assembled and tested microphone featuring a 4-JST SH connector. This connector provides 3V, GND, DAT, and CLK connections to create a flexible mic arrangement with one of the JST-SH cables. This microphone breakout offers an onboard solder jumper that allows the microphone to be changed from the left to the right channel. The PDM microphone breakout operates within a 1.8V to 3.3V voltage range and a 1MHz to 3.25MHz clock rate range with a 0.6mA current. This microphone offers a 61dB Signal-to-Noise Ratio (SNR) and -26dBFS sensitivity. The PDM microphone breakout is available in dimensions of 14mm x 14mm x 4.5mm.
