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
