First I have torxis/invenscience 12vdc servos. They are powered via 12vdc and at full load draw approximately 5 amps. So first question is how much current can the new ezb4 put out via its pin header. I plan to power ezb4 with 12vdc so hence the question.
Second question is a little more complicated for me at least. So I understand the ezb4 is wifi capable. Is it possible to use for telepresence? I guess what I mean is if I'm at work on my companies network is it possible to remote into ezb and see through the robots eyes/cameras? If so how would I go about doing it? VPN? I would like to be able to do this from my iphone or Samsung galaxy 3 tablet. Anyone care to take a crack at either of these. Anxiously awaiting ezb4's arrival.

Vcc = Vin
Ground = Ground
Signal = 3.3v when high.
Vin is the input voltage to the EZ-B. This can be 4.5v to 16v however 7.2v is recommended. If you put 12v in you will have 12v on the Vcc pins of each digital port.
***edit *** I see you're only using 2 servos... so the 20amp restriction wouldn't affect you....
Maximum current is in the table near the top of the datasheet.

The information you have requested is in the manual. Both DJ and myself have directed you to the manual because it's explained in there. There's no point in either of us copying what we can link to (not to mention the formatting if copied and pasted is all wrong in the forum to on the datasheet)
It's all under Electrical Characteristics;
Voltage input (Vin): 4.5-16v DC
Vin Continuous Current Draw: 5A
Vin Current Spikes: 20A
Vcc Continuous Current Draw: 1A
Vcc Current Spikes: 3A
Digital I/O TTL Voltage level: 1.6-3.6v (5V tolerant)
ADC Voltage level: 0-3.6v (5V tolerant)
The statistics speak for themselves. DJ has credit for 94 questions answered and I have credit for 182 questions answered (questions which were marked as requiring assistance, the reality of it is the numbers are much much higher). As can be seen in DJ's post, your second question, which isn't answered in a tutorial or datasheet, was answered. There is no cause for concern over the tech support you will get as far as I can see, if it's needed it is given. Where it's already answered previously or elsewhere then you'll be directed to the answer.
Edit: Looks like others answered while I was typing this...
I believe Rich that even in your "unboxing" video you were having troubles connecting to this device (albeit I guess was your fault- even after reading the manual I suspect). Maybe EZ- robot isn't for me, and judging by the posts coming in maybe this product isn't so EZ.
Everyone thanks for the reply's I will try not to post any questions regarding this product anymore as everything is in the "manual"
2) There were posts asking about tutorials a few days ago. In the past two days, there have been over 2 dozen updates to the website for new written tutorials and videos tutorials as per our release schedule. It is hard to read this image of our code repository updates, but changes have been occurring 24 hours per day for the last few days. To be clear - that means updates to the website for tutorial information has been happening even while you sleep...
3) The community is jam packed full of over 10,000 users from over 140 countries - and not all post but they watch our forum. Existing users (such as Rich and Dave, etc.) continue to progress and advance their robot and new users such as yourself join in. The manuals are put in place to address answers to beginner questions. If the information is there, it takes less effort to click and read than to write a post about information which is readily and easily available.
I see that you are frustrated with being told to check the manual. However, if the answer is in the manual, why wouldn't you check the manual? That's what the manual is for... The community is here to help support each other. The community is not volunteering to mimic items which are clearly posted in the manual and datasheet.
Do not run to another product to be disappointed with limited features. Simply understand that if information is clearly presented in a manual and that is the purpose of a manual
We have a beautiful and easy to navigate Learn section. I would recommend visiting the Learn section and spending some time reading the documentation and watching the newer videos. You'll be entertained and become an expert in no time
My unboxing issues were due to an incorrect password for my network, if you watch the start of the first video where I pull out the paperwork I throw them to one side and say that I don't need instructions. That issue was 100% down to the case sensitive password on my wifi, the issue was resolved after resetting the EZ-B and entering the correct password. I don't see how any of that is relevant though.
It actually took a few minutes to retype the information which was exactly where I told you it was. I know DJ doesn't have time to waste retyping things when a link is just as good. And, while I have no problem explaining things in detail when needed, if it's already explained I'll post a link. It isn't as if the information you were after is difficult to see in the link given!
We are not here to spoon feed you. As it's been said numerous times, if the information is already there somewhere then we will point you to it. If it isn't then we will answer the question. However, you cannot expect us to do it all for you, you will need to do some of the reading or some of the work yourself.
You have asked numerous questions in the past and you have received answers to all of them. I honestly have no idea why you are now posting that you don't get the tech support/help required. You have received accurate answers to all topics started. I have previously linked you to other topics which held the answers and there was no attitude afterwards about not helping, how is this one any different to those?
It's very rare that anyone on here will just come out with "read the manual". To be fair it's usually me who answers a lot of the questions and I do say to read the manual or read the datasheet however if I am aware of where in the manual the answer lies I will also tell you that too. This community is unlike other online communities, we do not look down on new members or less experienced members, we do not refuse to help or come out with pointless remarks. There are hundreds and hundreds of topics which back this up.
Having said that, there is a zero tolerance policy and you will also find that people, myself included are less inclined to offer help if the poster has an attitude or is rude. Please bear this in mind.
2) The digital I/O voltage pin is same as VIN
3) The ADC, Camera, and i2c ports voltage pins are regulated to 3.3v
The LEARN button on the top menu of this website will bring you to the Getting Started Guide. There you will find videos that explain the EZ-B and for those who are in a rush - you will find the Data Sheet. Here is a direct link to the Data Sheet: http://www.ez-robot.com/Tutorials/Default.aspx?id=7
Answering questions in the forum outside of the DataSheet is bad news bears. If we answer a question and later need to update the datasheet, they will be out of sync. Like all products in the world, we provide a datasheet with technical information. We also go above and beyond by providing tutorial videos and explanations. You will find those in the Learn section.
You can access the LEARN section by pressing the LEARN button on the top of this website.
If you want to pull up or pull down, you do that yourself externally.
This is why I prefer to direct people to the manuals and documents. If I answer the question in the forum, it's written for ever and never updated. The manuals go through revisions with updated information based on usage data.
However it was a good discussion and one that needed to be had. It's important to know the limits and capabilities of both the V3 & V4. The change from the V3 in that the digital I/O voltage pin is same as VIN is huge. It's very easy to plug directly into a device and send the wrong voltage to it. For example I just did this to a servo yesterday while I was swapping out one of my V3's for a V4. I sent 12vdc to a servo I had previously installed and powered by EZB that was expecting 5vdc. I went to have a drink to calm down after that so I still don't know if it's damaged or not. Totally my fault but I simply forgot for a moment in my excitement about the change.
Anyway, we all process information and learn differently. Some need multiple forms of input to understand and sometime what your looking for in the "printed" information is overlooked or misunderstood. Also all of us have different levels of maturity and tolerance. Put all that together and we're just one big dysfunctional family.
Nothing's wrong here as I can tell. We're going alright. Let's keep it up and get through the growing pains together. Dad & Mom (EZ Robot crew) are doing a great and much appreciated job with an amazing product and company and trying to keep us all happy and safe and well fed at the same time.
