Re: RX and TX LED

 

I put a resistor and a 12v LED into the TX line to my 30mm x 30mm fan which blows directly on the final heatsink. I wanted to drop the voltage to the LED and now I can see when I am in TX and that the fan is running.

If 12V, maybe go to 3.3 to 4.7K.? Leds are fairly bright at a couple of ma?

Mike beat me to it, and with better. Resistor first, then wire to diode/s (raw voltage to flying leads not the best idea! :)
