Like the Nano, the Micro's size and male pin headers make it perfect for prototyping with a breadboard. However, Arduino also offers this board without headers pre-soldered.

The Arduino Nano and Raspberry Pi Pico support different input voltages, so they also use different power sources. However, they can both be powered with a 5V supply via their onboard USB ports.

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.
