Description

The module is equipped with a digital microphone with a range from 50 Hz to 15 kHz, and also with the I2S bus. Work voltage in the range of 1.6 V to 3.6 V.

The microphone input is located at the bottom of the board, therefore you should be mindful of the corresponding turning plate in the direction of the sound. The device works with the I2S bus and only works with devices on this bus, for example,Arduino M0,M0 FeatherorRaspberry Pi.

Connection

The module has a simple goldpin connectors for self-soldering - raster 2.54 mm, communicates via I2S. Description of the specific outputs is given in the table.

Pin Symbol Description
1 3B Power to the layout from 1.6 V to 3.6 V.
2 GND

The ground of the system.

3 BCLK

Bit Clock. The input coming from microcontroller

informing the microphone in data transfer mode.

4 DOUT Data output from the microphone.
5 LRCL

Left/Right Clock. Tells you when to start the transfer.

Low sends on left channel

and high state on right.

6 SEL

The selection of channel. Default in the low state

that is, the broadcasting is on the left channel.

When you connect to a high state it is transmitted

through the right channel.
