ESP32-S3 Feather (redux)
from Adafruit Industries · host Adafruit Industries
we spent today working on a ESP32-S3 feather. you may be thinking "hey wait didn't you already design one?" yep! but we had a hardware bug that increased deep-sleep power, and so we wanted to revise the ESP32-S2 feather first to fix it since the PCBs for the two designs are shared. now we have the new ESP32-S2 in the shop with the fix https://www.adafruit.com/product/5303 so we can respin the S3. even better, Espressif has started adding S3 support in a branch so we were able to test the GPIO, I2C, UART, NeoPixel, low power, and WiFi capabilities successfully. We've got a PR open to add this new board - it's very exciting! https://github.com/espressif/arduino-esp32/pull/6450 This board uses the only S3 mini module available right now, with 8 MB of Flash and no PSRAM. however, there's more SRAM on the S3 than S2 so its still very usable. when the PSRAM-containing mini module comes out we'll make a version with that too.
