Four-Panel Technical Product Infographic
Map a smartphone, camera, earbud, and keyboard across a 2×2 grid with realistic forms, exploded parts, dimensions, arrows, and black technical notes.

Prompt
Create one square black-and-white technical infographic divided into a clean 2×2 grid. Place a different realistic consumer product in each quadrant: an exploded smartphone at top left, a camera with lens and internal cutaway at top right, a wireless earbud with transparent housing at bottom left, and an exploded mechanical keyboard at bottom right. Surround every object with dense but organized technical-pen annotations, component labels, dimensions, scale markers, arrows, force or signal diagrams, and small sectional sketches. Add a simple hand-drawn boxed category heading in the upper corner of each panel. Keep the objects clearly visible beneath thin black linework on a pure white background, with crisp borders and restrained grayscale shading.
