1  Using Arduino / General Electronics / Diode for reverse current protection but voltage drop? on: November 15, 2012, 12:33:22 pm
Hi guys, I was wondering if you could help me out on a little circuit problem.  I want to start moving towards the ATTiny chips for some of my smaller projects.  However, being clumsy as I am, sometimes I do the pinout backwards when there's Dsub's involved since the pinouts are in reverse when looking from the back compared to the front...  In any case, I wanted to idiot-proof my PCB so that the chip will be protected when I reverse the leads by adding a diode.  However, if my understanding is correct, it will create a voltage drop on the line, so my chip will no longer be getting the correct voltage.

Am I right about my assumption?  And are there any ways around this?
