The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.

512KB SRAM and 16KB of RTC SRAM Dual-core CPU at 240 MHz clock speed USB-C programming port The Arduino Nano ESP32 is available to order today in the Arduino Store, starting at $18.

The board itself also has some differences from the original Arduino Uno. First of all, it has a USB type-C port, which is definitely a bonus.

Of course, you can’t easily overwrite the bootloader and fuses over the serial port to prevent you from bricking your device. The video below shows how to connect another Arduino to do the ...

The Arduino Uno R4 is to have a Renesas RA4M1 32-bit Arm Cortex-M4 microcontroller, and there are “no plans to discontinue the popular Uno R3” , according to Arduino, which estimates that R4 will ...

The board that started Arduino's Nano family, the Nano is a classic platform ideal for basic circuit building and breadboard prototyping. It's similar to the iconic Uno in a lot of ways.
