Topic: max ampere for VIN pin (Read 29133 times) previous topic - next topic


Yea, but I've had a 5 amp transistor blow up to protect a 2 amp fuse.  :D

Yeah, pretty much every 4N007 has a 30A "spike" current, and "spikes" can be loosely defined, in my example, I'm doing lots of PWM, so those "spikes" are very short, but very often =)



Just a thought - it's quite easy to solder a wire (or a 1-pin socket) to the back of the input jack on an Uno. That way, you can take off the input voltage before it goes through D1. I'm using that method to breadboard a multi-servo system. The servos are powered by a separate regulator, but it saves having two power supplies.

FYI The UNO uses a "M7" Diode.. 1A continuous.
