hi all,
very quick question to double check.
I’m setting up the electronics for my Phoenix Hexapod
I’ve got a SSC-32, BotBoard2 and 18 HS-645MG servos.
I’m planning on powering EVERYTHING with a FlightPower Evo25, 2170mAh, 2s, 7.4v Lipoly pack (25C continuous discharge).
Will this be too much juice for the servos?
This will work…

Feed the battery directly to the VL inputs, but feed the VS inputs from the regulators output.
Hi Robot Dude,
I’m just setting up a hexipod with 12x HS-645MG + 6x HS-475HB servos.
I was wondering if I would be better off using the ‘Adjustable HD Regulator’ or the ‘Adjustable 5vdc - 6.5dvc Regulator’ that has multiple inputs and outputs, as my current requirements will probably fall around 3A peak (during operation of 6 servos during a move command).
I’m thinking to use, either 7.2 Volt Ni-MH 2800mAh Battery Packs or 6.0Volt Ni-MH 2800mAh Battery Packs with it.
I would guess that the regulators are linear style and not switching due to the large heatsinks on them?
Which device would be more robust for higher use and current draws?
Thanks,
Kirk
The best regulator for hexapods in my opinion is the MX-07. It’s dual inputs both go to the battery and the dual outputs go to the two VS inputs on the SSC-32. Although the regulator can accept 12vdc as an input, the current capacity goes way down. The regulator is switching, not linear. It’s really designed for LiPo packs. It regulates the 7.4vdc down to 6vdc very well. If you are considering a 6vdc NiMH then just use it without a regulator. Works great, we do it all the time. 
I was leaning towards that one, thanks for sharing your experience.
If it is switching I believe I will get a little more run time if I use 7.2Vdc packs and regulate them down to 6.0Vdc for the servos, plus a more repeatable response from the servo’s due to running them at 6.0Vdc from beginning to end of operation. This seems correct to me, please tell me if my reasoning is not completely correct.
The 7.2V packs are listed to run ~8.68Vdc off the charger, has anyone tested this configuration and knows if the regulator, MX-07, could handle around 4-5A peak at this voltage.
I’d kind of like to setup the power system with a regulator as well, so in the future I could slap a LiPo stack onto the robot.
would i be correct in using the following connection, using the [size=150]Bot Board I [/size]and SSC-32.

just double checking!
Note for the bot board with an atom pro, you can not connect the PS2 to pins 4-7 as pins 6 and 7 are only 3.? volts. You need to move to another set and solder in at least one pull up resistor. There are a few threads on this. Good Luck
Kurt
can i connect the ps2 on another set of pins?
Yes, you will need to solder in a pull-up resistor on the data line. I think there is a tutorial somewhere, but I am all thumbs right now. One thread is: lynxmotion.net/viewtopic.php?t=4146
great thanks
Hi,
I plan to power on my CH3-R with this powering option.
9.0vdc to BotBoard2 Jumper VS=VL
6.0vdc to SSC-32 Jumper VS=VL
Is that possible or not?
Then a further question to the schematics from Jim specialy Image 3
Is that only applicable for the Mini-ABB or also for the BB2?

There is no difference as far as powering goes between the Bot Board and the Bot Board II.
You can get away with powering the Logic from the Servo supply unless you notice erratic operation or the servos going limp.
Hi Jim,
thx for that information. Is it possible to power on the BB2 and SSC-32 with two separatly 9.0vdc batterys on VL (one on the BB2 the second on the SSC-32) and the SSC-32 with the Servoinput from 6.0 - 7.2vdc?
Greatings
Matthias
yes, no problem.
I have a question that I don’t think is covered in the SSC-32 manual or any of the wiring diagrams. Hopefully I have not missed anything.
I would like to power VL and VS1 from one battery pack and just VS2 from a second battery pack. Due to the AXON controller not having power connections compatible with the Lynxmotion battery packs I have, I need to route everything into and out of my SSC-32.
The question is: Can I have the VS=VL jumper installed and VS1=VS2 jumper removed to get me VL and VS1 on one batter and VS2 on a separate battery? Will this work?
I looked at the docs and such I could find, but did not see where this particular configuration is mentioned - either as a no go or that it will work.

It will work and here’s the missing clue that eludes to this.
The jumpers are labeled
VL=VS1 <- note it does not say VL=VS
So VS1=VS2 can be removed and power applied to VS1 will be shared with VL.
Ahhhh! I did miss that detail. I hate when that happens. It’s good to know this will work and it will let me do what I need to do.
Thanks!

I would like to supply my SSC-32 with 9V on the VL terminal and a single 7.4 2S LiPo pack running through a MPI 6V regulator. The VS=VL shorting block will be removed, of course. Each lead from the regulator is rated for 5 amps. I am planning to run 4 HS-5990tg and 6 HRS-645mg servos. In addition, I want to hook this LiPo low voltage warning device heliproz.com/prodinfo.asp?number=335444 to one of the VS terminals.
Question 1: Does anyone see a problem with this setup?
Question 2: Should the VS1=VS2 jumper be installed? Maybe to balance the load?
I would leave the VS1=VS2 jumper off. Let the regulator handle the grounding for the higher current loads separately.
Thanks, Jim!
