The voltage might be too much..The servonaut runs via 12volt

I have a servonaut BMA pump controller in my roll on/off skip truck and it runs quite happily on 7.2V

Hello,

Servonaut runs with 7.2 or 12 Volt. You can switch.

Visit the servonaut - homepage to get more information about.
http://www.servonaut.de/shop/index.php?language=en

How it works with MFU - I don't know. I think you will find some more information in german foren as www.modelltruck.net or www.modelltruckforum.de. But those discussions are only in german language.

Maybe it helps.

Regards from Lübeck / Germany

You can, but you have to put some resistors on the LED's from MFU

Its going to depend on how many leds you run on one circuit, when I did the lighting on my servonaut unit I bought a package with 500 resistors that ranged from just a few ohms to thousands(maybe $10 at radio shack). The calculations aren't hard at all to figure it out just have to know the voltage of each led(not sure what the mfu leds are rated at) and the out put voltage of the unit(I used 7.2V and everything works fine). I'm sure someone will chime in with the formula, I can't think of it at the moment.

I'm sure there are some mistakes, so hopefully someone straightens my mistakes out

High

you can calculate the resistors with a LED-Calculator. You can search in the Inet.

I got a link to a German calculator - maybe it will help

This is the one I use when working out what Led's resistors and even wiring diagram:
