TinyS3 - ESP32-S3 Development Board

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!
