FeatherS2 - ESP32-S2 Feather Development Board

Meet the FeatherS2, an outstanding development board from Unexpected Maker in the popular Feather format. Built on the powerful ESP32 - S2, it's a real workhorse. With a whopping 16 MB of Flash memory for firmware and file storage and 8 MB of QSPI - based external PSRAM, you get huge storage buffers for your projects. This Feather comes equipped with two 3.3V regulators. One powers the board, ESP32 - S2, RAM, and Flash. The other LDO is for connecting external 3V3 modules, sensors, and peripherals. It has programmable EN control linked to GPIO21 and is connected to the S2's deep - sleep feature. So, when the S2 sleeps, the 2nd LDO shuts down automatically! Both regulators are ultra - low noise, have ultra - low quiescent current, and can handle up to 700mA output. The FeatherS2 also features the awesome STEMMA QT connector, a chainable I2C port. You can use it with all kinds of STEMMA QT sensors and accessories like OLEDs and Inertial Measurement Units. It's plug - and - play, thanks to its innovative chainable design and SparkFun Qwiic - compatible connectors. No soldering needed! Just plug in a cable and attach it to your MCU. You can also use SparkFun Qwiic boards and Seeed Grove I2C boards with an adapter cable. This board ships with the current beta version (beta 1) of CircuitPython 6.0 that supports the ESP32 - S2. Plug it into your computer, and it shows up as a USB flash drive. Copy your code or edit it right on the drive. Coding a microcontroller has never been this simple! You can update to newer versions of CircuitPython from circuitpython.org as they're released. There's also early ESP - IDF and Arduino support if you prefer C++ coding.

Using the FeatherS2 is a breeze. First, plug it into your computer. It'll show up as a USB flash drive. You can either copy your code onto it or edit the code directly on the drive. If you're using CircuitPython, it comes pre - installed with the beta 1 version of CircuitPython 6.0. You can update it to newer versions from circuitpython.org. For those who like C++, there's early ESP - IDF and Arduino support. When connecting external 3V3 modules, sensors, or peripherals, use the second LDO. Remember, its EN control is tied to GPIO21 and it'll shut down automatically when the S2 goes into deep sleep. To use sensors and accessories, connect them via the STEMMA QT connector. It's chainable and SparkFun Qwiic - compatible, so no soldering is needed. Just plug in a cable. You can also use SparkFun Qwiic boards and Seeed Grove I2C boards with an adapter cable. As for maintenance, keep the board in a dry and clean place. Avoid exposing it to extreme temperatures or moisture. If you're not using it for a long time, it's a good idea to store it in an anti - static bag.
