Pimoroni FEATHERS3-01 - FeatherS3 - ESP32-S3 - The FeatherS3 offers a powerhouse of features in the super popular Feather format offer a huge ecosystem of add-on boards, modules and FeatherWings!
The Pro ESP32-S3 Development Board in the Feather Format
Packed with amazing features and peripherals, wireless connectivity and stacks of Flash and PSRAM, all in the same tiny package size as the original TinyPICO!
Yup! The first one is for the general operation of the board and the ESP32-S3, PSRAM 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 IO39 + it’s connected to the deep sleep capabilities of the ESP32-S3, so if the ESP32-S3 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.
Yes! One of the biggest feature requests about the FeatherS2 was that the single STEMMA connector was connected to LDO1 instead of LDO2. That was by design as there are plenty of use cases where you want your external sensor or module to stay powered when your ESP32 goes into deep sleep.
To solve this on the FeatherS3 there is a second STEMMA connector!!! Now there are 2!
The second STEMMA connector (The vertical one) is connected to the second LDO for power, so any I2C modules/devices you have connected to the that STEMMA connector will automatically power down when the ESP32-S3 goes into deep sleep or if you disable the second LDO via IO39.
Both STEMMA connectors share the same I2C BUS along with the 2x I2C pins broken out on the pin headers.
Unexpected Maker ESP32-S3 boards can be used with CircuitPython, MicroPython, ESP-IDF or Arduino.
Your board ships with the latest version of CircuitPython with ESP32-S3 support.
It also ships with the UF2 bootloader, so you can easily update your board with the latest CircuitPython firmware, whenever you desire.
Just plug your board 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
If you need to grab the shipping CircuitPython code that comes with your board, you can grab the latest here
MicroPython has excellent support for the ESP32, and that includes the ESP32-S3.
If you would like to put MicroPython on your new board, please follow the flashing guide for your board from this firmware link and don't forget to erase your flash first!
For more information about developing projects on your new board, using MicroPython, check out the MicroPython documentation.
ESP32-S3 support in the IDF is part of the v4.4 release. The latest IDF is v5.0, but it's in early development, so I recommend you stick to the v4.4 release branch for the time being as there are some low level breaking changes in v5.
Check out the ESP32-S3 IDF docs for information on how to install it and develop for the ESP32-S3
If you have not already setup your Arduino IDE environment to work with ESP32, please follow the official Espressif ESP32 Arduino Core instructions to install it.
Arduino support for the ESP32-S3 is available in 2.0.3 and later. Please install the latest version to be able to select ESP32-S3 boards with the latest fixes and features.
