The devicetree nodes are 0-indexed, but if you look at the silkscreen on the board, the LEDs are 1-indexed:</p> <p><a href="https://www.nordicsemi.com/Products/Development-hardware/nrf52833-dk">https://www.nordicsemi.com/Products/Development-hardware/nrf52833-dk</a></p> <p>The docs are currently correct, as far as I can see. If I were to change anything I would change the naming on the DK itself. But, alas. They are out in the field now.</p> <p>Your feedback on point b) has been shared with the Dev Academy team.</p> <p>Thank you!</p> <p>Best regards,</p> <p>Raoul</p><div style="clear:both;"></div>
