The family of XIAO devices has a really small footprint. I wanted to use the ESP32-S3 for a decoder for powermeter readings via firmware from TASMOTA https://tasmota.github.io/docs/Smart-Meter-Interface/.
The availiable prebuild firmware can be flashed via “tasmotizer” or “ESP-flasher”. This is working for most ESP32 devices but not for the XIAO ESP32-S3.
Any hints / tipps?
You have to build it…
ESP32-S3~
Keeping the security improvements the S3 line now again features the dual core SoC with Bluetooth upgraded to V5 . Product page for ESP32-S3.
Use tasmota32s3- binaries for this line of chips.

Hi C64emu.
I had issues in getting a working install of Tasmota loaded onto the ESP32-S3 Xiao. With some help from the Tasmota Discussions page (follow Flashing Seeed XIAO ESP32-S3 with tasmota32s3.bin (or tasmota32s3.factory.bin) · arendst/Tasmota · Discussion #21539 · GitHub) I was able to resolve the problems and now have a working ESP32-S3 with version 13.4.0.
Hope this helps.
