If the project requires less storage and the space given is small, then it is better to go with Nano as the size of Nano is small and the specifications are more or less similar to Uno.A serial to TTL converter is needed to write programs in the Nano breadboard. The programs can be written in Uno by connecting it to the PC directly and making it work.When the program is up and running, the variables can be created and manipulated in Nano due to its SRAM space and Mega systems while it does not happen in Uno. Uno has 2kB SRAM space while Nano has 8kB SRAM space in the system and hence it can store more data than Uno. Static Random Access Memory is used in Arduino systems.Both Nano and Uno have a clock speed of 16MHz and the memory also remains the same.Nano has a flash memory of 32kB with a preinstalled bootloader while Uno is 32kB without a bootloader.Uno uses a regular USB port while Nano uses a Mini USB port. Among the digital pins, 6 have PWM in Nano and Uno. Uno has the same 14 digital pins and only 6 analog pins. There are 14 digital pins used and 8 analog pins used in the system. Nano has a large number of pins among both.If the working space is smaller, it is better to go with Nano. Both can be connected to the computer using a Standard A/B USB cable that is a part of the microcontroller system. The price of Uno comes from $20-$23 while Nano is much less and close to 7$. The size of Nano is 1.7” x 0.73” and Uno is 2.7” x 2.1” that shows Nano is much smaller than Uno.Let’s discuss the top comparison between Arduino Nano vs Uno: And a regulated 5v can apply through pin number 27.Key Differences between Arduino Nano vs Uno A 6-20v unregulated power can be applied through pin number 30. The working voltage of Arduino nano is 5v and powerd through the mini B Usb. For example Mosi pin connected to the Mosi pin of second Arduino board and sck to sck pin. To reprogramming the bootloader connecting this pins to another Arduino board with same icsp pinout. This pins are useful for programming Arduino board in the situation of error in bootloader. It consists of the pinout of MOSI,MISO,SCK,RESET,VCC,GND. Is a AVRtiny programming header in the arduino board. The icsp pin is stands for in circuit serial programming. If the 27 th pin is Low or 0 volt, the IC get restarted. Most commonly the reset can done though a switch connected to the 27 th pin of Arduino. Which means the program will be restored or restarted as like the initial uploaded state. Reset pin is doing the job of totally reseting the microcontroller ( atmega328p). Using for receive and sending serial data.Īrduino nano icsp pinout ARDUINO NANO ICSP PIN the low input voltage is 0v and high at 5v. These pins can be used as an input or output. GND- represented as the ground or negative supply. Vin- The pin provides the input voltage to the Arduino when the time of using an external power source.ĥV- This is the regulated or fixed voltage used to power the microcontroller and other components.ģ.3v- is generated by the board voltage regulator with a very small current.
