How to Use Nano V3.0 Super Mini: Examples, Pinouts, and Specs

The Nano V3.0 Super Mini, manufactured by Estardyn, is a compact microcontroller board based on the ATmega328P microcontroller. It features USB connectivity for programming and debugging, making it an excellent choice for embedded systems and compact projects. Its small form factor and robust design allow it to be easily integrated into a variety of applications, from DIY electronics to professional-grade prototypes.

• Embedded systems and IoT devices
• Robotics and automation projects
• Wearable electronics
• Sensor data acquisition and processing
• Prototyping and educational purposes

The following table outlines the key technical details of the Nano V3.0 Super Mini:

The Nano V3.0 Super Mini has a total of 30 pins. Below is a detailed description of the pinout:

1. Powering the Board:

   • Connect the board to your computer via the Mini-USB port for programming and power.
   • Alternatively, supply power through the VIN pin (7-12V recommended) or the 5V pin (regulated 5V).

2. Programming:

   • Use the Arduino IDE to program the Nano V3.0 Super Mini. Select "Arduino Nano" as the board and "ATmega328P" as the processor in the IDE settings.
   • Install the necessary USB drivers if the board is not recognized by your computer.

3. Connecting Peripherals:

   • 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.

4. Uploading Code:

   • Write your code in the Arduino IDE and upload it to the board via the USB connection.
   • Ensure the correct COM port is selected in the IDE.

• Avoid exceeding the maximum current rating of 40 mA per I/O pin to prevent damage.
• Use a decoupling capacitor (e.g., 0.1 µF) near the power pins to reduce noise in sensitive circuits.
• When using the board in a permanent project, consider soldering the headers for a secure connection.
• If using the board with a battery, ensure the voltage is within the recommended range (7-12V).

The following example demonstrates how to blink an LED connected to pin D13:

// Blink an LED connected to pin D13
// This example toggles the LED on and off every second.

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

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
}

1. Board Not Recognized by Computer:

   • Ensure the USB cable is functional and supports data transfer.
   • Install the correct USB drivers for the Nano V3.0 Super Mini.

2. Code Upload Fails:

   • Verify that the correct board and processor are selected in the Arduino IDE.
   • Check the COM port settings and ensure no other application is using the port.

3. Power Issues:

   • Confirm that the input voltage is within the recommended range (7-12V for VIN).
   • Check for loose connections or damaged components.

4. Unresponsive Board:

   • Press the reset button to restart the microcontroller.
   • Re-upload the code to ensure the program is correctly loaded.

Q: Can the Nano V3.0 Super Mini operate at 3.3V?
A: Yes, the board provides a 3.3V output pin, but the microcontroller operates at 5V. Ensure peripherals connected to the I/O pins are 5V-tolerant.

Q: How do I use the ICSP header?
A: The ICSP header can be used for programming the microcontroller directly or for SPI communication. You'll need an external programmer for ICSP programming.

Q: What is the maximum current the board can supply?
A: The onboard voltage regulator can supply up to 500 mA, but this depends on the input voltage and heat dissipation.

Q: Can I use the Nano V3.0 Super Mini with a breadboard?
A: Yes, the board's small form factor and pin layout make it breadboard-friendly. Use male headers for easy insertion.

By following this documentation, you can effectively integrate the Nano V3.0 Super Mini into your projects and troubleshoot common issues with ease.
