I am not aware of drawing more than 1A over PCB traces. We are planning to use ACS712 hall effect current sensor linked below:


Can anyone help with the width and depth of the traces for such higher currents?

How far should I place other components including microcontroller?

Should I have heat sink or such arrangements?

Or should I solder copper wire with 5mm thickness to connectors and place sensor module above it?

Thanks in Advance

  • \$\begingroup\$ Hello @Andyaka thanks for the reply. I've seen one of the calculator over here. 4pcb.com/trace-width-calculator.html \$\endgroup\$ – Abhishek Parikh Feb 12 '18 at 10:48
