Nano

The cheapest and simplest of the new lineup is the Nano Every, which costs $9.90 and is based on the ATMega4809 microcontroller. It runs at 20 Mhz and comes with 48KB of Flash and 6KB of RAM. The Nano 33 IOT costs $18, offering Wi-Fi and Bluetooth connectivity.

Which is the smallest Arduino?

Beetle – The Smallest Arduino Board

Beetle is an extremely the smallest Arduino Leonardo board. It derives its core notion from minimalism without compromising functionality. It comes with Atmel AtMega32u4 @16MHz clock time and has expanded amounts of interfaces: 10 digital pins, 5 analog pins and 4 PWN pins.

Is Nano same as Uno?

There are 14 digital pins used and 8 analog pins used in the system. Uno has the same 14 digital pins and only 6 analog pins. … Uno has 2kB SRAM space while Nano has 8kB SRAM space in the system and hence it can store more data than Uno.

What is difference between Arduino and Raspberry Pi?

The main difference between them is: Arduino is microcontroller board, while Raspberry Pi is a microprocessor based mini computer (SBC). The Microcontroller on the Arduino board contains the CPU, RAM and ROM. All the additional hardware on Arduino Board is for power supply, programming and IO Connectivity.

Is Arduino Nano better than Uno?

One key difference between the two is that the Nano has two extra analog pins, A6 and A7. Only the Nano has this, because the Uno uses an Atmega328P with 28 pins, where the Nano’s microcontroller has 32. For the most part, a Nano makes a good replacement for an Uno, especially when you need breadboard compatibility.
