Driving USB LED from duet

Is it possible to take 5V from the expansion pins; as well as one of the PWM pins and drive a LED (It looks almost like a USB stick with 3x yellow LED's and a little black block saying 150) with varying brightness?
Yes, probably. In many ways setting up basic LEDs is the same as setting up a fan. Since duet switches pwm on the negative side you can source your voltage elsewhere and then use a fan or heater pin to control it.
In fact if you configure it as an actual fan it can show up as a slider on the web interface for dimming.
