Unfortunately I was runing in to a problem. I have a humanoid robot with 18 servos (probably she will get 2 more).
So I was happy to receive my new EZ-B4.
First I found a 10A fuse in the "power adaptor"
I did not want the whole plastic staff on to my robot. (Less weight and I did not have space for it as well.)
So I got the board naked. eyeroll
I did not want to use the power plug aswell. So I got rid of it. I was soldering cable straight to the board.
I used a bench powersupply for the tests.
I have noticed a diode in the power input (D1).
The diode marked for A7 p39. Is it 1n4007?
Because that is an 1A diode? confused
Any way My servos 6-7.4V
2S lipo straight off the charger 8.4V (nominal 7.4) mad
So I should use UBEC. (Castle Creations BEC-PRO 20Amp)
But I do not want to use it. (More weight, and the effiency of the BEC in not 100% so I do not want to waste the battery power for heating the air)
But instead of that I will use
2s LiFePo4 straight off the charger 7.2v (nominal 6.6V)
I will power it not from the power input pins of the board.
Instead i will connect the negativ for the input pin. But the positive straight for the top board servo pins (3 pins where is the smilie on the top board)
Oh yeah with an 15A fuse.
And I will set the voltage monitor for 5.6V
And the other thing. Because the speaker left in the plastic. Is there any one tried an 1w 8Ohm speaker on it externally?
If you have any toughts please share with me. Thanks.
(How you can recognize stupid people? ........... They never ask.)

i hope so haha
injoy your pizza
Nomad, You're such a good sport. RR! However you still love him..... like the rest of us.
Hi Alan. Yes I have the software actually the whole cd. If you want I can upload it. No bother. But I think he should change for ez-b. And not playing with some robo basic stuff.
I am not bored just not a rich guy. I think and ask before doing any damage.
Is there something information about the Hitec servos? With standard 1-2ms it turns only +-60 degree. Any chance to squeze out 0.55ms-2.45ms from ez-b?
Richard you where right it is an yellow 20 Amp fuse.
Thanks, if you check the post I linked, the robot belongs to his University, so he needs to prove that the motherboard is bad before he can replace with an EZ-B, which was also my suggestion.
I have no idea about your servo question. Jeremie could probably answer it.

@ Richard R
Do you supply more than 6V via EZB4 to your HS-805BB servo?
If so , how much?
@Aerius No, I use a 6V 12a SLA battery in my inMoov
