Arduino Nano Pinout

Interactive Arduino Nano Pinout Map

The Arduino Nano Pinout tool provides a comprehensive interactive overview of the ATmega328P microcontroller connections. By clicking on any specific pin, users can instantly view technical details such as PWM capabilities, power limits for the 3.3V and 5V outputs, and specific notes regarding UART pins during USB flashing. This visual guide helps developers quickly identify available GPIOs and understand hardware constraints without having to consult complex datasheets manually.

Technical Specifications and Capabilities

The tool highlights the specific capabilities of the Arduino Nano, including its 22 digital pins and 8 analog inputs. It clearly differentiates between standard GPIOs and special cases like A6 and A7, which are restricted to analog input only. Furthermore, it provides critical information on power management via external sources and identifies shared functions, such as the SPI Clock on pin D13, ensuring you can design stable hardware for your IoT projects.

Which pins on an Arduino Nano support PWM?

The Arduino Nano features 6 PWM-capable pins, which are essential for controlling components like motors or LEDs. Our interactive tool highlights these specific pins, allowing you to quickly identify them and ensure your hardware setup is correctly configured for pulse width modulation requirements.

Can I use A6 and A7 as digital GPIO pins?

No, the A6 and A7 pins on the Arduino Nano are designed for analog input only. They lack the internal drivers required to function as digital GPIOs. Our tool clearly marks these limitations so you can plan your wiring correctly before building your project.

Are the UART TX and RX pins usable as GPIO?

Yes, both the TX and RX pins function as standard GPIOs. However, they are occupied during the USB flashing process for serial communication. Our tool provides specific warnings about these pins to help you manage your connections effectively during development.

What is the maximum current for the 3.3V output?

The 3.3V output from the onboard regulator can provide a maximum of approximately 50 mA, depending on whether you use the CH340 or FT232 chip. This information is included in our tool to help you avoid overloading the board's power circuitry.
