Use wider tracks/polygons/multiple vias for higher currents #45

Only 1 via and narrow tracks are used for connecting high currents.

There are calculators available to estimate conductor and via properties.

One example: image

KiCad also has PCB Calculator: image

Use more vias for driver power input:

Make driver output tracks wider or probably better is to use filled zones:

Use wider tracks and more vias for motor drivers power:

  1. Try to connect other motor drivers the same way as the first one. 3 vias is probably enough, but you can add more.

  1. Use wider tracks or polygons for lower current power connections also. +5V on both sides and +3.3V on MCU side.
