How it looks
Real geometry: CORE3588 copper, drawn from our board file (2D plan view)
One net on CORE3588, in amber: PERIPH_3V3, the 3.3 volt supply for the extra chips. Every amber bit (tracks on top and bottom, vias, pads, small copper areas) is one connected piece of copper. The other 447 nets are grey.
1PERIPH_3V3 starts near the USB-C power input...
2...feeds the Wi-Fi module...
3...the switch that powers the SD card...
4...the motion sensor, and more.
How it works
Where it fits
Nets come from the netlist. Before routing they show as airwires; nets with shared rules form a net class.
