I am building LED strip controller with esp32 and 5V-5A power suplly. During prototyping I somehow touched output (5V) wires from power supply, made short circuit and they started to melt down. Power supply shoud have short circuit protection and I think, this was due to thinness of jumper wires I used during protoryping.
However, I would like to add fuse to avoid fire things up in some improbable similar situation. I am thinking about adding fuse on input or output of power supply. I measured power supply input current with fully bright strip (~130mA). What do you think is the best solution - add 5A car-like fuse on output or 160mA 250V fuse on input of power supply?
