The Arduino SuperMini USB-C is an ultra-compact ATmega328P development board designed for embedded projects, compact electronics, robotics, sensors, and breadboard prototyping. It delivers full Arduino Nano compatibility in a significantly smaller footprint.
- ATmega328P microcontroller running at 16MHz
- Compact SuperMini size — only 21.72 × 26.16mm
- USB-C interface with CH340G USB-to-serial chip
- 14 digital I/O pins including 6 PWM outputs
- Headers supplied unsoldered for flexible builds
Quick Start
1
Install Arduino IDE
Download and install the Arduino IDE if you do not already have it.
2
Connect via USB-C Cable
Use a data-capable USB-C cable for programming and serial communication. Some USB-C PD laptops, chargers, and smart power supplies may not correctly negotiate power with these Nano development boards. If the board does not power on or connect, try a USB-A to USB-C cable or a standard 5V USB power source.
3
Select Board
Go to Tools → Board → Arduino Nano.
4
Select Processor if Upload Fails
Try Tools → Processor → ATmega328P Old Bootloader.
Please note: Headers are supplied unsoldered. USB-C cable not included. Some systems may require CH340 drivers.

Getting Started
1
Install Arduino IDE
Download and install the latest Arduino IDE from the official Arduino website.
2
Connect via USB-C
Use a data-capable USB-C cable and connect the SuperMini to your computer. USB provides standard 5V power for programming and normal USB operation.
3
USB-C Compatibility Note
Some USB-C PD laptops, chargers, and smart power supplies may not correctly negotiate voltage with these Nano development boards. If the board is not detected, powers intermittently, or shows 0V output on smart USB-C power supplies, try using a USB-A to USB-C cable or a standard fixed 5V USB source instead.
4
VIN Power Option
If powering the board through VIN instead of USB, supply 6–12V through the VIN pin.
5
Select Board Type
In Arduino IDE, go to Tools → Board → Arduino Nano.
6
Select Processor if Upload Fails
If uploads fail, try Tools → Processor → ATmega328P Old Bootloader.
Please note: Some computers may require the CH340 USB driver for detection.

Common Questions
Are the headers pre-soldered?
No — the included headers are supplied unsoldered so you can install them in your preferred orientation.
Which board should I select in Arduino IDE?
Select Arduino Nano, then choose ATmega328P or ATmega328P Old Bootloader if uploads fail.
Does it work with standard Arduino libraries?
Yes, this board is compatible with standard Arduino Nano sketches, examples, and libraries.
Do I need CH340 drivers?
Most modern systems install drivers automatically, but some systems may require manual CH340 driver installation.
Why does it not power on from some USB-C chargers?
Some USB-C PD chargers and smart USB-C ports may not supply power if they cannot negotiate correctly with the board. Use a standard 5V USB source or USB-A to USB-C cable for best compatibility.
Please note: This is a third-party Arduino-compatible development board and is not manufactured by Arduino.
