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.Key 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
