board is to provide an example of the decoding and streaming of digital MEMS microphone outputs.</p> <p>The STEVAL-MKI117V2 demonstration board hosts the MP45DT02 (top-port digital microphone), working as a sensor, and the STM32F107RC microcontroller, working as an audio decoder. These microphones are analog-to-digital transducers, in other words, they are able to sense sound pressure and convert this signal into a digital signal using the PDM technique.</p> <p>The STM32 microcontroller decodes the PDM signal coming from the microphones and streams the audio via the USB. The STEVAL-MKI117V2 demonstration board is a sound card automatically recognized by the PC as an audio device. The connection is made through a USB cable which also supplies the board and then streams the collected audio.</p> <p><strong>Applications:</strong> Mobile terminals, Laptop and notebook computers, Portable media players, VoIP, Speech recognition, A/V eLearning devices, Gaming and virtual reality input devices, Digital still and video cameras, Antitheft systems</p> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Features</h3> <ul> <li>Powered and connected to PC through USB</li> <li>Sound card automatically recognized by the PC as an audio device</li> <li>The onboard microphones are digital MEMS devices</li> <li>MEMS microphones provide a high frequency data stream (1 to 3.25 MHz) of 1-bit digital samples (PDM technique)</li> <li>Audio collected from the microphones is sent to the PC through the USB</li> <li>LED status indicator</li> <li>RoHS compliant</li> </ul> <h3 class="toc-item xs-pb2 xs-border-bottom">Ships With</h3> <ul> <li>Demonstration Board</li> </ul> <div id="devtool-required-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Required Tools</h3> <div id="devtool-required-devtools-content"></div> </div> <div id="devtool-accessory-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Accessory Tools</h3> <div id="devtool-accessory-devtools-content"></div> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Documents</h3> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Application Note</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/document/application_note/DM00046968.pdf" target="_blank">AN4041: APWlink+ microphone USB demonstration boards based on the MP34DT01, MP45DT02, or MP34DB01 (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Data Sheet</h4> <div class="attachment "> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/document/datasheet/DM00025467.pdf" target="_blank">MP45DT02 MEMS audio sensor omnidirectional digital microphone (pdf)</a> </div> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/document/datasheet/CD00220364.pdf" target="_blank">STM32F107RC Mainstream Connectivity line, ARM Cortex-M3 MCU with 256 Kbytes Flash, 72 MHz CPU, Ethernet MAC, CAN and USB 2.0 OTG (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">User Manual/Guide</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/document/data_brief/DM00051595.pdf" target="_blank">DB1601: MEMS microphone demonstration board based on the MP45DT02 and STM32 (pdf)</a> </div> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Downloads</h3> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Bill of Materials</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/document/bill_of_materials/steval-mki117v2_bom.pdf" target="_blank">STEVAL-MKI117V2 BOM (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Design Package</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://www.st.com/st-web-ui/static/active/en/st_prod_software_internet/resource/technical/software/sw_development_suite/apworkbench.zip" target="_blank">APWorkbench Audio Processor Workbench software development suite (zip)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Schematics/Layout Files</h4> <div class="attachment "> <i class="fal fa-file-archive"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/layouts_and_diagrams/board_manufacturing_specification/steval-mki117v2_gerber.zip" target="_blank">STEVAL-MKI117V2 gerber files (zip)</a> </div> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/layouts_and_diagrams/schematic_pack/steval-mki117v2_schematic.pdf" target="_blank">STEVAL-MKI117V2 schematics (pdf)</a> </div> </div> </div> <div style="clear:both;"></div> <div style="font-size: 90%;">Tags: MP45DT02, stm, stm32, analog_demo_boards, mems_and_sensors_mems_inertial_measurement_units</div>
