Fuse max Amp for 1206L?

Hi

I am building a RP3 board for direct control using PCB schematic provide in the download section (https://www.nanodlp.com/download/schematic.png)

I planning to use a 12v power supply for the stepper.  What is the max current value of the fuse 1206L?

Thanks

As the 1206 is only supplying the Raspi ( at 5VDC) for logic 2.5 amps should be more than enough. Maybe increase to 3 if you're running a cooling fan or similar
Its also probably a good idea to join the ground line of the 12 volts supply to the ground line of the 5VDC / RP3 as well
