All the codes written for Uno will work with Nano due to the less number of analog pins in Uno.If the need is a fabrication, it is better to go with Nano and if it is needed for developing projects and codes, Uno works better with the capability.
Thus, it does all the work done by Uno with the storage and memory capacity but looks to adjust with less space in the system.
ARDUINO NANO PINOUT SERIAL
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: Key Differences between Arduino Nano vs Uno
