A well-configured board DTS typically includes:

- An Arduino-compatible connector definition,
labeled as `arduino_header` (or other supported connectors)
labeled as `arduino_header` (`compatible = "arduino-header-r3"`)
- Optionally, connector mapping nodes for PWM/ADC pin association and channel derivation (commonly `arduino_pwm` and `arduino_adc`)
- Bus defaults via node labels such as `arduino_serial`, `arduino_i2c`, `arduino_spi`
- A built-in LED via the `led0` alias (recommended)
