Q1. I am working on a EZ-robot project that will force me to use the LARGER Servo (59mm x 29mm x 55mm) 40kg torque and thus wish to control the servo from the EZ-B v4/2 Wi-Fi Robot Controller BUT with a separate POWER SUPPLY.
Any TIPS, do and don’ts, wiring Infor, types lipo etc power pack which is best etc. would be very helpful. You cannot give me too much information ?

Q2 I may be forced to use a SECORD EZ-B v4/2 Wi-Fi Robot Controller, thus any TIPS, do and don’ts, wiring Infor etc. would be very helpful on how to use, run and program TWO EZ-B v4/2 Wi-Fi Robot Controller would be a great help. You cannot give me too much information ?

Lots of thanks for any help

I have found a few conversations, tutorials and activities that may help with your question. Take a look at these links. I've sorted them by what I believe to be most relevant but that is not always the case as I'm still learning.

Also, consider reviewing the Learn section for informative lessons and activities. Check it out!


Main tip is that everything should have a shared ground (or earth as I think you call it in the UK).



thanks for taken the time to help, will read and learn from your data


Take a look at this thread for information about using 2 (or more) EZ-B's. It is documented in each EZ-Builder object, but the script function is a little hard to find.



For your servos you can build a power distribution board or make up a harness from thicker gage wire. Your servos should connect to the high current supply plus and minus. Ground everything together as guru said. A digital output will go from the EZB to the servo signal wire.

There are lots of ways you can go but this might get you started. Come back with any questions


Thanks to ALL the members help, busy learning a bit more each day

I love my build hobby and thanks to your help it is slowly moving forward

Keep up the good work
