The Arduino Nano SuperMini packs the same ATmega328P chip as the standard Nano into a much smaller footprint. It's ideal for embedded projects where space is tight — wearables, small enclosures, compact sensor nodes. It has a USB-C port for programming and power, and the CH340 USB-to-serial chip means no driver headaches on most systems.
- ATmega328P — same chip as Arduino Nano and Uno
- USB-C port for programming and 5V power
- CH340 USB-to-serial (drivers included automatically on most OS)
- 14 digital I/O pins, 8 analogue inputs (A0–A7)
- SPI, I2C and UART interfaces
- 16MHz crystal oscillator
- 3.3V and 5V onboard regulators
- Compact board — smaller than standard Arduino Nano
Specifications
What's in the box
USB-C cable not included — available separately in the store.
Great for
Getting started
- Install Arduino IDE
Download from arduino.cc. The Nano SuperMini uses the same board package as Arduino Nano — select Arduino Nano under Tools → Board.
- Connect via USB-C
Use a USB-A to USB-C data cable. The board will appear as a COM port. If not detected, install the CH340 driver for your OS.
- Select the processor
Under Tools → Processor, choose ATmega328P (Old Bootloader) if sketches fail to upload with the default setting.
- Upload a sketch
Try File → Examples → Basics → Blink. Hit Upload. The onboard LED should start blinking.
Common questions
What's the difference between this and a standard Arduino Nano?
Same ATmega328P chip, same pinout and IDE compatibility. The SuperMini is physically smaller and has a USB-C port instead of Mini-B. Fewer through-hole pads — some boards have pins only on one long edge, or no pre-soldered headers.
Will my existing Nano sketches work?
Yes, if you select Arduino Nano in the IDE. The ATmega328P is identical, so all library and sketch compatibility carries over.
The board isn't detected when I plug it in — what should I do?
Install the CH340 driver for your OS (search "CH340 driver" — widely available). On Mac, also check System Settings → Security & Privacy after install.
Upload fails — what do I try first?
Try Tools → Processor → ATmega328P (Old Bootloader). Also confirm the correct COM port is selected under Tools → Port.
Good to know: Headers may or may not be pre-soldered depending on the variant received — check the product photo. The board is 5V I/O only — do not connect 3.3V-only sensors directly to I/O pins without a level shifter.
