PCB thickness is chosen when ordering; it is not determined automatically by the schematic.
For this controller, select:
- Finished PCB thickness: 1.6 mm
- Copper weight: 1 oz
- Layers: 2
1.6 mm is the common default and is strong enough for the ESP32 sockets, headers, and wiring. It also works with most ordinary mounting hardware and enclosures.
You can verify the selected thickness in three places:
- The PCB manufacturer’s order form under PCB Thickness.
- The manufacturer’s final order summary.
- With digital calipers after receiving the board; a nominal 1.6 mm board may measure slightly above or below 1.6 mm because of manufacturing tolerance.
Do not confuse board thickness with copper thickness. “1 oz copper” is about 35 µm (0.035 mm) per copper layer.
