FeatherS2 - ESP32-S2 Feather Development Board

4 items left

Introducing the FeatherS2 - The full-featured ESP32-S2 based development board in a Feather format from Unexpected Maker. The FeatherS2 is a power house, fully souped up with 16 MB of Flash memory (for firmware and file storage) and 8 MB of QSPI-based external PSRAM so you can have massive storage buffers.

This Feather comes with two 3.3V regulators: The first one is for the general operation of the board and the ESP32-S2, RAM and Flash. The second LDO is for you to use to connect external 3V3 modules, sensors and peripherals, and it has programmable EN control tied to GPIO21 and it’s connected to the deep sleep capabilities of the S2, so if the S2 goes into deep sleep, the 2nd LDO is automatically shut down for you! Both regulators are ultra low noise and have ultra low quiescent current, and both support a maximum of 700mA output.

This Feather also comes with our favorite connector - the STEMMA QT, a chainable I2C port that can be used with any of our STEMMA QT sensors and accessories. OLEDs! Inertial Measurment Units! Sensors a-plenty. All plug-and-play thanks to the innovative chainable design: SparkFun Qwiic-compatible STEMMA QT connectors for the I2C bus so you don't even need to solder! Just plug in a compatible cable and attach it to your MCU of choice, and you’re ready to load up some software and measure some light. Use any SparkFun Qwiic boards! Seeed Grove I2C boards will also work with this adapter cable.

    The FeatherS2 ships with the current beta version (beta 1) of CircuitPython 6.0 that supports the ESP32-S2. Just plug your FeatherS2 into your computer and it will appear in your filesystem as a USB flash drive! Just copy your code over, or edit your code directly on the drive. Coding a microcontroller has never been easier!

    As newer versions of CircuitPython are released, you are able to update as you require from circuitpython.org

    There is also early ESP-IDF and Arduino support if you prefer coding in C++.
