Reply to "Design of a $10-20 DCS-TIU Port Tester Tool?"

I'm still not happy with the LED situation.

Per the schematic, the 2 cathodes (pin 1) are connected together. For virtually all LEDs, the flat-side of the body is the cathode. On the PCB drawing, the square-pads (presumably pin 1) are indeed connected together... yet the flat side of the LED silkscreen is on the right side? confused

As for the on-off "switch" presumably you are assuming someone is using a 1-cent shunt to install on the 2-pin header. I'm sure there are many variants but you can also get 2-pin switches that have similarly narrow profiles in the same footprint.

Next thing you know the peanut gallery will be demanding an LED to indicate power is on! eek
