Seeed Studio XIAO ESP32S3 (Sense) support in EI

Will the Seeed Studio XIAO ESP32S3 (Sense) be supported in EI eventually and when expected?
Thanks

The best I can say is that ESP32S3 support is in the works. However, we do not have plans to officially support the XIAO ESP32S3 board at this time.

Hello @shawn_edgeimpulse,

I’m writing to inquire about Edge Impulse’s support for the ESP32-S3 microcontroller. I’m interested in using the ESP32-S3 for my next project and was wondering if you have an estimated timeline for when it might be supported.

Thank you for your time and consideration.

Best regards,
Lhagva

Hi @lhagva,

The ESP32-S3 is supported if you use the C++ or Arduino library. We do not have plans at this time to create official firmware for any ESP32-S3 boards.

Hi @shawn_edgeimpulse
Thank you for your reply.
I have downloaded C++ library of the audio classification project from the Edge impulse, and when I set target as ESP32S3 then compile returns follwoing errors. Please note that it worked perfect for ESP32. Please tell me how to fix this issue. Thank you

Hello @AIWintermuteAI
Thank you very much for your help! I was able to compile the code successfully thanks to your explanation.
