NanoS3 is the world’s smallest full ESP32-S3 based development board in a module format. It has 27x IO broken out, an onboard 3.3 V LDO, battery charging, onboard RGB LED, and ultra low deep sleep current. The NanoS3 includes an onboard 3D high gain antenna, and the NanoS3 uFL includes an u.FL connector for an external Antenna. NanoS3 is basically a TinyS3 as a module, but smaller - 28 x 11 mm. All you need to add is a USB connector of choice if one is required, and some buttons if needed.
