  (text "How to read this schematic:\n- Each box below is a sheet. Double-click it in KiCad (or turn the PDF page) to open it.\n- Parts connect by NAME: two labels with the same text are the same wire.\n- Flag-shaped labels (e.g. USB_DP) connect across sheets. Plain labels stay on one sheet.\n- +5V, +3V3, VBUS and GND symbols connect everywhere.\n- An X on a pin means 'intentionally not connected'."
