You can intercept the main 5V line upstream of the circuit and cut the 5V track that will become the INPUT. The other part of the track connects to the OUTPUT. GNDs can be soldered to any point as long as they are solidly connected.
see the main picture as reference
Hello Edoardo,
thanks for the project!
You wrote: "cut the 5V track". You mean it should be installed in serial on the 5V line?
Or, can i solder it at the marked place (please see picture) so in parallel on the 5V line?
Thanks!
Hi, it must be installed in series to the main 5V line. You need to cut the 5V line after the power switch and solder the e-fuse board across the two sections.
Ok thanks!
