I asked last week about the old stranded servo voltage. Now does anyone know the old HD servo voltage range?

I'm guessing Operating Voltage: 4.8V to 7.2V. Same as the "new" HD servos. I'm not sure if the new ones in the store are going to be any different from the old ones. I don't think they switched those. They are/were private labeled Futuba servos.

Antron is right these servos run between 4.8 - 6v but can handle 7.2 no problem.... Servos in this category are pretty much all the same... they all run basically the same voltage range whether they are Tower pro, Hitec, Futaba, etc

Thanks for the info and conformation.
I've decided to input the Vin voltage to my V4 EZB at just about 6.5 vdc. This voltage will run everything nicely I had previously attached to the digital I/O ports except my MP3 Trigger and the 2.5 Amp Motor Controller I bought from EZ Robots a while back.
I'm still not sure about the Vin voltage range of the 2.5 Amp Motor Controller but the first day I powered up my new V4 EZB I pumped 12dv through it and it seemed to work OK. At least it didn't have any short term bad effects. However to be safe I decided to use it's onboard voltage regulator and feed it's electronics from the external 12vdc I have connected to it for the motor voltage. I just disconnected the wire I had connected from the digital I/O pin (leaving the ground connected between the two) and pushed the little white button next to the connectors. Works great and the board gives itself the designed voltage needed.
Also that same day I burnt up my MP3 trigger by also pumping 12vd through it. However I plan to use EZB's on board audio and attach it to an amp. I didn't cry over that brain fart to much. *blush*
So now I'm going through and double checking all my voltage requirements on all devices attached and being fed off the digital I/O ports. Like I stated above; looks like I'll be ok now with about 6.5 vdc. I have this adjustable voltage regulator between my 12vcd power supply and the EZB V4. About 9 USD on Amazon. It only will handle up to 2amps (3 if you push it) but shouldn't pull that much (however I do plan to amp clamp it to get a true reading):
Dork Buck Regulator
Module Model:LM2596 Buck Converter+Voltmeter
Input Voltage: DC 4.0~40V
Output Voltage: 1.25V~37V
Output Current: 2A(normal and stable), 3A Max.
Display Color: Red
The above regulator is not the only thing out there. so if you want something like this simply get one that will give you the voltage and amperage you need. *cool*
