- content/edge/l3/edge-car-tracker.md, written from the evidence notes - product image of the SIM7080G Cat-M module, cropped to 640px, with a caption naming what it is and that it is a product image - referenced from the edge overview - original kept in sam/CAR_GPS_TRACKER so the project repo documents its own build
