Adafruit ESP32-S3 Feather Dev Board w/ STEMMA QT – 8MB Flash

Description

The Adafruit ESP32-S3 Feather condenses the power of Espressif’s latest ESP32-S3 microcontroller into the Feather form factor, designed for rapid prototyping and deployment. Its dual-core 240 MHz processor provides the computational headroom needed for complex tasks like data processing, TLS encryption for secure MQTT, and managing multiple wireless connections simultaneously. Native USB-C integration simplifies development workflows, allowing the board to function as a composite USB device for direct programming, serial communication, or emulating peripherals like keyboards and mass storage.

Engineered for low-power IoT deployments, the board features integrated LiPo battery management with active monitoring via a MAX17048 fuel gauge chip, enabling precise battery percentage reporting over I2C. The Feather’s standardized pinout and extensive ecosystem of “Wings” (add-on boards) allow for scalable system design, from adding displays and sensors to integrating LoRa or cellular connectivity. Its FCC/CE-certified radio module ensures reliable, compliant wireless performance for commercial products.
