Adafruit FeatherS2 - ESP32-S2 Feather Development Board

The FeatherS2 is a full-featured ESP32-S2 development board in a compact Feather format. It boasts 16 MB of Flash memory for ample firmware and file storage, along with 8 MB of QSPI-based external PSRAM for extensive storage buffers.

This board is equipped with two ultra-low noise 3.3V regulators: one for general board operation and the second, which is programmable, for external 3V3 modules and peripherals. The latter is connected to deep sleep capabilities, automatically shutting down to conserve energy.

Featuring the versatile STEMMA QT connector, it enables chainable I2C connections without soldering, ensuring seamless integration with sensors and accessories such as SparkFun Qwiic and Seeed Grove I2C boards.

Pre-installed with CircuitPython 6.0, the FeatherS2 appears as a USB flash drive on your computer, allowing for easy code editing and uploading. The board also supports early ESP-IDF and Arduino if you prefer C++ coding.
