Nom Nom R29

Greetings.

Can't seem to find the value of R29 (it was an addition back in the day). Any help is appreciate.

Is it ok to leave it without a jumper if I don't want pulsing LED?

thanks

From the docs:

There are two ways you can use an LED indicator for the Speed control.

Method 1 – Make R29 a 1k resistor. Wire the "LS" pad to the anode of a 3 or 5mm diffused LED. 
Wire the cathode of that LED to ground. This method will show a square wave output so it will blink 
on and off.

Method 2 – Make R29 a 1M resistor. Wire the "LS" pad to the circuit shown below. This will give the
LED some ramp up and down on its illumination so it is not quite so "square".

Thanks for the reply, saw that. So I HAVE to use R29?

No. Only if you want an LED indicator for your speed. It has no effect otherwise.
