Feather of the Day: Adafruit ESP32-S3 Feather with 4MB Flash 2MB PSRAM and STEMMA QT #Adafruit #Feather

The Adafruit Feather ecosystem is so rich with hardware diversity, we wanted to share them, one each day. Today is the Adafruit ESP32-S3 Feather with 4MB Flash 2MB PSRAM – STEMMA QT!

The Espressif ESP32-S3 has arrived in Feather format – and what a great way to get started with this powerful new chip! With dual 240 MHz cores, WiFi and BLE support, and native USB, this Feather is great for powering your IoT projects.

That’s right – it’s the new Adafruit ESP32-S3 Feather with dual core and native USB – this version comes with 4 MB flash, and 2 MB PSRAM compared to the Feather ESP32-S3 with 8MB Flash / no PSRAM version here.

Native USB means it can act like a keyboard or a disk drive, and no external USB-to-Serial converter required. WiFi and BLE mean it’s awesome for IoT projects. And Feather means it works with the large community of FeatherWings for expandability.

The ESP32-S3 is a highly-integrated, low-power, 2.4 GHz Wi-Fi/BLE System-on-Chip (SoC) solution that has built-in native USB as well as some other interesting new technologies like Time of Flight distance measurements and AI acceleration. With its state-of-the-art power and RF performance, this SoC is an ideal choice for a wide variety of application scenarios relating to the Internet of Things (IoT)wearable electronics, and smart homes.

The Feather ESP32-S3 has a dual-core 240 MHz chip, so it is comparable to ESP32’s dual-core. However, there is no Bluetooth Classic support, only Bluetooth LE. This chip is a great step up from the earlier ESP32-S2! This ESP32-S3 mini-module we are using on the Feather comes with 4 MB flash and 2 MB PSRAM, as well as lots of 512KB of SRAM so it’s perfect for use with CircuitPython support or any time massive buffers are needed: for fast memory access use SRAM, for slower-but-roomier access use PSRAM. It’s also great for use in ESP-IDF or with Arduino support.
