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.
