Exclamation Brain Wiring Diagrams

Hi,

Here are a few Diagrams for wiring, hope this helps

Standard Receiver ( PPM )


Futaba S-Bus Receiver


Spektrum Genuine DSM2 and DSMX Satellites

Great job! Thanks. It is good to see the servo layout when pluging them in. Less confusion as to where servos 1, 2, and 3 should should be located.

Great diagrams Fabien,

I have the Brain connected with the Spektrum AR7100R and i'm find that the system retains power when switched off and i can't seem to find a reason why.

I am running straight Lipo 2S voltage to everything and i'm running a Futaba voltage step down for the tail servo which is connected inbetween the Brain and servo.

I assume that even though the RUDD/AUX2 outputs from the AR7100R are 5.2 regulated that the Brain will supply the straight 2S lipo voltage to everything?

Hi,

mmm it depends on how you wire the unit.

If you have direct HV output for cyclic servos and low voltage output ( 5.2V f) for tail, then the best is to use only the HV wires on the receiver side to power the Brain and make sure to have removed the tail " + " (red) wire fromt he plug so it does not feed for example HV throught he elevator connector and in adition 5.2 V via the tail.

I will check the exact spacs of your receiver and will make a wiring diagram tonight for you,

Best regards,

fabien

Online look at HV BeastX wiring setups posted here on Helifreak. You would normally split the signal wires off the cyclic leads so that you have 7.4v going to your cyclic servos only. The Brain + tail servo would be powered from the regulated 5.2v side sending just signal to the cyclic. Common ground is maintained through the battery. You might have to use the aux channel and the tail channel to power the Brain for redundancy.

Hi,

sorry for my late answer.

As you have a stepdown regulator between the Brain and the tail servo, you have to remove the red wires on the AUX 2 and RUDDER lines between receiver and Brain, so all servo bus is powered staight from the 2S lipo and the tail servo will be happy with the step down regulator.

On another hand, for that kind of configuration, you can also get rid of the 7100R as it is just useless here for that configuration ( as you can not use the 5.2v regulated outputs), and use satellites instead on the Brain

You will then just need to keep the stepdown between brain and tail Servo.

Most important is to keep signal and ground wires ( normally signal sould be enough but by precaution only remove the 5.2 V red wire) betwen AR7100R and BRain if you keep the receiver

BEst regards,

Fabien

I'm going to put a Brain on my Synergy N5C and will be running HV to my cyclic and tail servos with a Gryphon Duo regulator for my throttle servo. It's my first nitro and have never used a regulator. I didn't find any documentation on the Gryphon Duo. Does the regulator simply plug in between the Brain Throttle output and throttle servo?

You are going to have to run the power and the ground to the regulator and the signal wire to the brain. Otherwise the HV will also go to the throttle servo from the brain.

All these diagrams are located in your Brain software, Basic Wizard step #3 "Receiver Configuration"

hi yes it is located in the software but why not sticky it for a quick reference for the guys that have a problem and come on asking for help and a diagram.
as fabien took time out to do them for the first of us to use them on first release especially as he doesn't work for msh is bit of a waste, these pictures are as good to the newby as his tuning guide is to the more experienced.

just wanted to say that I think it's hilarious how i stumbled onto this thread. I'm a neuroscientist and am just doing some basic research on the internet. and Voila! a Helifreak thread pops up at work! I can't escape you, Helifreak!

Brain wiring diagram. LOL!

Hi, i will use a voltage regulator from Gryphon.
Should i remove the red wire between reg and ikon for servo 1, 2, 3 and only provide power on CH3/SREC or should i keep all the red wires and provide power width CH3, SRV1, 2, 3.

The Cyclic servos will be powered by the reg (6v) and the tail servo directl by the brain (5.2v).

Thank you for your feed-back.
