• Wearable electronics
• IoT (Internet of Things) devices
• Portable data loggers
• Robotics and automation
• Prototyping small-scale embedded systems

The Nano Supermini is built to deliver reliable performance in a compact form factor. Below are its key technical details:

The Nano Supermini features a total of 30 pins, including power, digital, and analog pins. Below is the pinout description:

The Nano Supermini is easy to integrate into a variety of projects. Follow these steps to get started:

• The board can be powered via the USB port or an external power source through the VIN pin.
• Ensure the input voltage is within the range of 7-12V when using the VIN pin.

• Connect the Nano Supermini to your computer using a USB cable.
• Open the Arduino IDE and select Tools > Board > Arduino Nano.
• Choose the correct port under Tools > Port.
• Write or load your program and click the Upload button.

• Use the digital and analog pins to connect sensors, actuators, and other peripherals.
• For PWM control, use pins D3, D5, D6, D9, D10, or D11.

Here is a simple example to blink an LED connected to pin D13:

// This program blinks an LED connected to pin D13 on the Nano Supermini.

void setup() {
  pinMode(13, OUTPUT); // Set pin D13 as an output pin
}

void loop() {
  digitalWrite(13, HIGH); // Turn the LED on
  delay(1000);            // Wait for 1 second
  digitalWrite(13, LOW);  // Turn the LED off
  delay(1000);            // Wait for 1 second
}

• Avoid exceeding the maximum current rating of the pins (40mA per pin).
• Use appropriate resistors when connecting LEDs or other components to prevent damage.
• Ensure proper grounding for stable operation.

1. The board is not detected by the computer.

   • Ensure the USB cable is functional and properly connected.
   • Install the necessary drivers for the Nano Supermini in the Arduino IDE.

2. Program upload fails.

   • Verify the correct board and port are selected in the Arduino IDE.
   • Press the reset button on the board before uploading the program.

3. The board overheats.

   • Check for short circuits in your circuit connections.
   • Ensure the input voltage does not exceed the recommended range.

4. Analog readings are unstable.

   • Use a capacitor between the analog input pin and ground to filter noise.
   • Ensure proper grounding of all components in the circuit.

Q: Can the Nano Supermini run on battery power?
A: Yes, the board can be powered using a battery connected to the VIN pin, provided the voltage is between 7-12V.

Q: Is the Nano Supermini compatible with Arduino shields?
A: Due to its compact size, the Nano Supermini is not directly compatible with standard Arduino shields. However, it can be used with custom shields or breakout boards.

Q: How do I reset the board?
A: Press the reset button on the board, or connect the RESET pin to GND momentarily.

Q: Can I use the Nano Supermini for wireless communication?
A: Yes, you can connect external wireless modules (e.g., Bluetooth, Wi-Fi) to the board via its digital or UART pins.

By following this documentation, you can effectively utilize the Nano Supermini in your projects. Happy tinkering!
