Description
The Supermini Nano V3.0 is an ultra-compact development board built around the ATmega328P microcontroller, the same core as the classic Arduino Nano but redesigned in a significantly smaller form factor . It features a modern USB Type-C connector and an onboard CH340G USB-to-UART converter for programming and serial communication . Running at 16 MHz with 32KB of Flash memory, this board delivers full Arduino Nano functionality in a space-saving design suitable for compact embedded projects, wearables, and tight prototypes .
