Introducing the FeatherS3 - The pro ESP32-S3 Development Board in the Feather Format now with a u.FL connector instead of an onboard antenna, for the times when you want to connect an external antenna for longer radio range, or for putting your S3 boards inside a case/enclosure.
The FeatherS3 ships with the latest version of CircuitPython with ESP32-S3 support.
It also ships with the UF2 bootloader, so you can easily update your FeatherS3 with the latest CircuitPython firmware, whenever you desire. Just plug your FeatherS3 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 the FeatherS3, you can grab the latest here.
You can also use Arduino 2.0.3 or later, which has added S3 support. There is also ESP-IDF and an early MicroPython port available as well. Visit the TinyS3 product page for more details.
