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.
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
support if you prefer coding in C++.
