Checkbox 1
The board is not plugged into a circuit
The first step in verifying that the microcontroller works correctly is to isolate it from other components.
If you start with a microcontroller connected to a circuit and to power, unplug it first.

Make a visual inspection.
- If the Arduino MKR WiFi 1010 is connected to power, unplug it.

- If the Arduino MKR WiFi 1010 pins are connected to a circuit (e.g., using the Arduino MKR Connector Carrier or a prototyping board), unplug it.

Once the microcontroller is unplugged from power and any other component, move forward to the next steps.
