Step 14: Fields

the fields on the board: adom-fields solves the current density of every loaded net, the heat flow in each copper layer with the vias, and the temperature over the board; the AI reads the issues and walks the board in the app on camera

Adom Fields current and heat screen on the final board: VBUS and GND at 0.5 A peak 40 A/mm2, +3V3 at 0.1 A 12 A/mm2, under 1 C rise in still air. The 'no TVS' tag on J2 is expected: ESD protection is on the USB daughterboard.
