Evaluation Kit with Audio support

Hello,
We are looking for an evaluation kit with the following requirement for a voice application (VoIP).

  1. STM MCU and WiFi-Hallow with RTOS support
  2. Board should allow to connect audio module (Codec/SLIC)

Any suggestions, We are looking at [MM6108-EKH08-05US-02], Any better suggestions with audio ?

Hi @raghavactpl

The U575 included in that kit has 2 SAI blocks, which I can be configured I2S and PCM. This should cover both a standard codec and a high voltage SLIC interface. You will need to assess the relevant peripherals to ensure they meet the requirements for your application.

The U575 is well tested on our side for HaLow support. It forms a key part of our micro-controller SDK test infrastructure.

Note, that this kit uses a module which is tuned for 902-928 MHz only (Mouser appears to have an error) - so will work for the Americas, Australia and some of Asia.

Thank you for the quick response.

  • Do you suggest any audio daughter card which which can fit into U575 ?
  • Hope i can use this SDK “GitHub - MorseMicro/mm-iot-sdk” ?
  • Does the SDK support all the API’s such as socket API’s provided by LwIP ?

Yes, that SDK is FreeRTOS based with options for LwIP or FreeRTOS+TCP.

That SDK does not have an audio application example, and we don’t have any recommendations for an audio daughter card.
