Arduino Super Mini Nano V3 ATmega328P Development Board
Compact Improved Version Microcontroller Core Module
This Super Mini Nano V3 board is a compact, breadboardfriendly development board based on the ATmega328P microcontroller [citation:7][citation:8]. It delivers the same powerful functionality as the larger Arduino boards in a spacesaving design, ideal for embedding in projects or prototyping on a breadboard [citation:2][citation:3].
Compact and BreadboardFriendly Ideal for space-constrained projects and permanent embedding.
ATmega328P Core Reliable 8bit AVR microcontroller running at 16MHz.
Board features a CH340G USBtoserial chip for easy programming and communication [citation:1][citation:5][citation:8].
Select "Arduino Nano" board and "ATmega328P" processor in the Arduino IDE [citation:5][citation:8].
I/O pins operate at 5V logic level - use level shifters for 3.3V devices.

Troubleshooting
Board not detected:
- Install CH340G USB driver if not automatically recognized [citation:2][citation:6].
- Use a data-capable USB cable (not just charging cable) [citation:5].
- Try a different USB port.
Upload fails:
- Select Tools → Board → Arduino Nano.
- Select Tools → Processor → ATmega328P (or Old Bootloader for some clones) [citation:5][citation:8].
- Check correct COM port selection.
