Pin 2 on the Arduino schematic is really GPIO2 on the NINA, therefore it should not be labeled GPIO34. This is confirmed by the fact that the pin numbering on the Arduino schematic matches the pin ...

You can select pin numbering in Tools > Pin Numbering option: By Arduino pin (default): Standard for Nano boards by Arduino. By GPIO number (legacy): Standard for most ESP32 boards. Regardless of ...

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 Nano Every is a pin-equivalent substitute, so previous code and wiring will still work. Arduino has also swapped out the Nano's mini-USB connector in favor of micro-USB.
