NanoS3 - ESP32-S3 Module

by Unexpected Maker

NanoS3 is the world’s smallest, fully-featured ESP32-S3 module!

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 Nano, and it's drop in compatible too!

Note that this module is designed for embedded use - for a standalone board with USB-C check out TinyS3 or the mighty ProS3!
