Microprocessor board suggestions for Audio focused TinyML / AI

[mzvitzf]

Hi All,

I’m trying to hunt down the best board for my new project. Basically I need the following functionality either on the board or via add-on boards. I can see a few possibilities but I haven’t had much experience so I thought it best to ask. Thankyou!

Requirements

• TinyML (processed onboard) 0.5 and above Tops
• Generate and encode sinewave between 18kHz - 21kHz
• Microphone input
• Class d Speaker out (=>3w preferably)
• Low power
• Ethernet (RJ45)

Not a requirement but would be great

• POE
• Wifi
• Low budget

Hello @mzvitzf ,

Sorry for the late reply.

Seeing your requirements, all I can think of is the u85 IoT: B-U585I-IOT02A - Discovery kit for IoT node with STM32U5 series - STMicroelectronics

But it has not ethernet port and not the right audio codex.

This board is what we use for all AI audio event sound detection use case, so it is compatible with model zoo deployment for audio event detection use case as well. You can take a look here: https://github.com/STMicroelectronics/stm32ai-modelzoo/tree/main/audio_event_detection/deployment

You can also take a look at the STM32U575I-EV but it is somewhat pricy and does not have a RJ45, a audio out and is not low power...

Have a good day,

Julian
