![]() ![]() The size of the Nano board is slightly larger than the Pro Mini board.The differences between Arduino Nano and Pro mini are listed below: What is the main difference between Arduino Nano and Arduino Pro Mini? The Arduino Pro Mini includes 8 analog pins, 14 digital Input/Output pins from which 6 are PWM pins. The Arduino UNO includes 6 analog pin inputs, 14 digital pins, a USB connector, a power jack, and an ICSP (In-Circuit Serial Programming) header.The size of the Arduino Pro Mini is very small compared to the Arduino UNO.The oscillator frequency of Arduino Pro Mini is 8MHz, while the oscillator frequency of Arduino UNO is 16MHz.Arduino Pro Mini operates at the voltage of 3.3V, while Arduino UNO operates at the voltage of both 3.3 and 5V.The differences between Arduino UNO and Pro Mini are listed below: We need to solder the headers while implementing the board in our projects.ĭrawback: The Built-in programmer, shield, and USB port are absent in Arduino Pro Mini.Īrduino Pro Mini board is shown below: What are the differences between Arduino UNO and Arduino Pro Mini? Here, IDE stands for Integrated Development Environment. The Arduino Pro Mini is organized using the Arduino (IDE), which can run on various platforms. It is primarily used in compact size projects due to its small size. For 5V, we are required to use the Arduino Pro Mini 5V board. If we want to use the operating voltage of 3.3V, we need to use the Arduino Pro Mini 3.3V board. It is preferred by advanced users for greater flexibility and small size. The connectivity and functionality are the same as other Arduino boards. However, for further queries, communicate with us.The Arduino Pro mini is a small Arduino board based on ATmega328P or Microcontroller. We hope that we have explicitly covered the two modules. The above boards are useful for advanced users and simple DIY projects. But, for less advanced projects, you can settle for the pro mini. Moreover, the NANO has superior RAM to the Micro version. However, the Nano is better for applications requiring fitting in a solderless breadboard since it’s small and has other additional features. Has a USB support (Micro-USB Connector), and FTDI forms the USB connectionīoth boards run on Arduino software and thus can perform in equal measure. Operating Voltage- 7V to 9VInput Voltage- 5VĪnalog Input pins count – 6 No analog output PinsĪnalog Input count- 8 No analog output pins What are the Differences between Arduino Pro Mini vs Nano?įig 2: Both boards are useful in DIY projects FeaturesĪTMega328P and ATMega168P microcontroller It provides a reference voltage to the board It switches the LED ON and OFF depending on the board’s condition. These are essential in initiating an interrupt They are useful in receiving and transmission of the board’s TTL serial data. They maintain the board’s analog input voltage between 0V and 5V. It is useful in resetting the microcontroller. Vin is the input voltage pin connecting to an external power source of 7V to 12V. Next, we have the 5V for supplying a regulated power supply voltage. Also, there’s the 3.3V pin that receives minimum voltage from the voltage regulator. Lastly, GND is the board’s, Ground Pin. Lastly, there’s a RESET pin for setting the microcontroller.Moreover, we have the Data Terminal Ready (DTR) pin for resetting the board and inputting the bootloader for the Arduino pro mini programming.In addition, there’s Pin I2C which enables I2C communication.The LED goes on when the pin is high and off when the pin is low. Further, we have Pin 13, which features a built-in LED. ![]() These are imperative in supporting SPI communication. Also, there is Pin 10 (Slave Select), Pin 11 (Master Output/ Slave Input), Pin 12 (Master Input/ Slave Output), and Pin 13 (Serial Clock).You use these pins with the analogWrite function to give an 8-bit PWM output. Triggering these pins prompts an interrupt. ![]()
