Digital MEMS microphone expansion board based on MP34DT06J for STM32 Nucleo

X-NUCLEUS-CCA02M2

Overview

The X-NUCLEO-CCA02M2 expansion board has been designed around MP34DT06J digital MEMS microphone.

It is compatible with the ST morpho connector layout and with digital microphone coupon boards such as STEVAL-MIC001V1, STEVAL-MIC002V1 and STEVAL-MIC003V1.
The X-NUCLEO-CCA02M2 embeds two MP34DT06J microphones and allows synchronized acquisition and streaming of up to 4 microphones through I²S, SPI, DFSDM or SAI peripherals.
It represents a quick and easy solution for the development of microphone-based applications as well as a starting point for audio algorithm implementation.

Main features

2 on-board MP34DT06J digital MEMS microphones
6 slots to plug in digital microphone coupon boards such as STEVAL-MIC001V1, STEVAL-MIC002V1 and STEVAL-MIC003V1
Synchronized acquisition and streaming of up to 4 microphones
Free comprehensive development firmware library and audio capture plus USB streaming sample application compatible with STM32Cube
Compatible with STM32 Nucleo boards
Equipped with ST morpho connector (upwards and downwards)
Equipped with Arduino UNO R3 connector (upwards) to allow multiple boards
RoHS and WEEE compliant

Touch screen issues
Are there any API functions for touch panel power management in wince 6.0 that can be called by applications? For example, functions like TouchPanelEnable. In the touch panel driver, there are functio
EMC microcontroller macro definition study notes
Preface: I have been organizing and producing some macros of EMC programs these days, and found that this thing is really useful beyond imagination. The following is mainly based on EM78P260. In fact,
EZ-USB FX2LP series chip CY7C68013A
I'd like to ask, does anyone know more about the EZ-USB FX2LP series chip CY7C68013A? This chip has three types of pin numbers, namely 56-pin, 100-pin and 128-pin. The interface mode I use is GPIF mas
A set of envelope lines (motor speed 3000rpm, i.e. frequency 400Hz) passes through the second-order low-pass filter circuit R1=R2, C1=C2, etc.
There will always be a phase shift after filtering, right? The two figures in the figure are the comparison of the results before and after. I want to calculate the theoretical value of the phase shif
The incompatibility between SMIC and TSMC is very beneficial to my country's chip design industry
What SMIC needs is time and better management. Whether Wang can improve SMIC's management is a question. His previous record at Huahong NEC was not very positive. For SMIC's customers, changing the le
How to test the withstand voltage characteristics of general ceramic capacitors
This capacitor is a multilayer ceramic capacitor with the technical parameters of 10nF/±10%/50V. Test purpose: I want to know the maximum voltage value that can be loaded on both ends of the capacitor
