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.

Ok, we’ll come clean. [Design Build Destroy] didn’t really add any memory to his Arduino Nano. But he did get about 1.5K more program space when compared to the stock setup.

Another pin you can use on the Nano to power it up is the 5V pin (located on Pin 27, close to the VIN pin at the end of the board). This pin mostly serves as a power output pin that supplies power ...

This is the SB116, an 8-bit programmer’s calculator powered by an Arduino Nano. It features a 128 x 64 pixel monochrome OLED display and can be powered by either a USB port or three AAA batteries.

Other features of the Maker Nano RP2040 small board which measures just 49.53mm x 21.08mm in size include support for the Arduino IDE, CircuitPython and MicroPython.
