Introducing the TinyS3 - The Tiny Mighty ESP32-S3 development board in the TinyPICO 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.

TinyS3 is the latest in Unexpected Maker's super popular range of "Tiny" development boards. It's 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!

The TinyS3 ships with the latest version of CircuitPython with ESP32-S3 support. It also ships with the UF2 bootloader, so you can easily update your TinyS3 with the latest CircuitPython firmware, whenever you desire. Just plug your TinyS3 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 can update as you need from circuitpython.org If you need to grab the shipping CircuitPython code that comes with the TinyS3, 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.
