A Feather form factor ESP32-S3 dev board with 1S LiPo battery monitoring.
This board uses an ESP32-S3-MINI-1-P1N8
module with 8MB of flash and no PSRAM.
When the board is booted into debug by holding BOOT
and pressing the RESET
button the USB-Serial chip on the USB port exposes a serial connection. This can be used to easily flash new firmware.
Flashing
Flash using Tasmota Web Installer and select Tasmota ESP32-S3 option.
For esptool.py download f.e. tasmota32s3.factory.bin
and run esptool.py write_flash 0x0 tasmota32s3.factory.bin
To put ESP32-S3 in flash mode GPIO0 needs to be pulled low.
