ESP32-S3FN8

Great, absolutly!!!
I have 3 Soundtouch, currently running connected to a docker image. This solutions beats everything.
Does it run with an ESP32-S3FN8 with NO PSRAM. I found this device:

M5Stack Capsule Kit with M5StampS3 SKU: K129
https://shop.m5stack.com/products/m5stack-capsule-kit-w-m5stamps3

This controller is delivered with case and small. It could be clued at he back of the sound touch and connected to the USB port( for power delivery).

Thank you for your work....

I looked in the platform.ini and asume it would be [env:s3-8mb]

A few things, in order of importance:

One stick serves all your speakers. SixBack isn't one board per speaker — a single ESP32 runs the local server and talks to all three of your SoundTouch systems over the LAN, the same way your one Docker instance does today. So the goal is to place that single stick where it has the best Wi-Fi link to your router, powered from any ordinary USB charger — not attached to a speaker. Mounting it on the back of a SoundTouch puts it wherever the speaker happens to stand, which is usually the worst spot for Wi-Fi.

The SoundTouch USB port wouldn't help there anyway. Per Bose's own documentation it's a service port for setup, software updates and diagnostics only, and is explicitly not designed to power or charge devices — so it isn't a dependable power source for a stick.

On the board itself: the M5StampS3 uses the ESP32-S3FN8, which has no PSRAM, and the S3 build needs PSRAM (its TLS / Spotify / OTA paths rely on it). Any ESP32-S3 module with PSRAM (an …R8 variant) works with the existing env:s3 build. Supporting every possible board isn't something we take on — the source is open if you want to port a specific one.

Thank you, I followed your suggestions and ordered the ESP S3 with PSRAM and installed everything.
Easy installation and configuration, everything works again, danke
