Because of the Nano's small form factor, it doesn't have much space to accommodate a jack. There are, however, still three other ways you can power your Nano: via the USB port, VIN pin, and 5V pin.

While the pinout is very similar to the Arduino Nano’s, there are four (12-bit) analogue inputs rather than eight (10-bit). Some digital GPIO pins are numbered differently too.

The Arduino Nano and Raspberry Pi Pico have distinct pin configurations. The Nano includes 14 digital pins (for both digital input and digital output components) and eight analog pins.

The power of Espressif’s ESP32-S3 meets Arduino’s unmatched customer experience, documentation and community — all in the compact form factor of the Nano. Provides support for both ...
