Hi DJ,
Would you help to answer my question as below :
1. I'm making a robotic but it has over 23 servo ports. Is it need to buy one more EZB4 to extend the servo ports? if yes, how to connect and let the ARC to know the extend servo ports?
2. EZB4 can support the heavy duty servo (VDC 12V)?
3. Will it reduce the power if servo ports are full ?
Thanks for your attention.

1) Two (or more) EZB v4/2 linked together to take advantage of more ADC, i2c, UART and camera ports without having to connect to the EZB's over WiFi.
a) In other words, how do you connect two or more EZB's to a PC through USB? My robot has a dedicated Mini ITX motherboard w/8GB of RAM, 2.8 GHz Quad-core Processor and four USB 3 ports + two USB Type C ports.
3) The configuration has a camera connected to one of the EZB's camera ports (unless it is easier and more efficient to have the EZB v4/2 access a Web Cam connected to one of the USB ports on my ITX motherboard.
I have spent a day trying to find lessons and tutorials on how to accomplish the above, but am not seeing a complete picture.
Check this thread:

I read through that thread before I posted my question here. It was confusing as I did not see (undertand) how to go about connecting two EZBs to USB on my PC, bypassing WiFi and also using a camera.
If you have a pc in your robot, use a usb camera. That’s why it’s okay to lose the camera port on the ezb because you simply add a usb camera in exchange.
If you don’t find the information that you’re looking for, it can’t be done
I completely understand that I loose the option to connect a camera to the EZB once I have connected the EZB to my PC via USB. I also understand that I would connect a webcam to a USB port on my PC. What I am not clear about is how do I go about linking more than one EZB together if I am connecting one of them to my USB port on my PC.
Believe me when I say this, If you were in Michigan right now, I would let you smack me upside the head.
You can't chain them together.

One uart ttl per ezb and voila!
I just bought an amazon basics usb hub last week for $7 Canadian - that’s like 35 cents usd
Okay, I am not looking for the cheapest solution, but I found this on Amazon. Would this work?
I just don't know how the USB-to-Serial drivers are for that chip in particular. I've had troubles with prolific chips in the past. Maybe Will can offer some advice when it comes to the driver, it could just be built into windows but I doubt it. The unit might come with a driver CD though.
In reference to my post #19, the USB to TTL serial cables that I listed has 4 wired leads (+5V, GND, RXD and TXD). Is that sufficient? I do see some with six lead wires (GND, CTS#, 3.3v, TXD, RXD and RTS#).
Also... Is this the driver set you recommend?

And yes I believe that is the download site for prolific.
I was hoping you could answer this question. I have two EZ-B v4 on hand without the EZ-B v4/2 Comm Upgrade and was wondering if the upgrade was necessary if I am going down the path of utilizing the USB to TTL serial cables? Is there any advantage of using the v4/2 with a direct USB connection?
Note that I did order one EZ-B v4/2 as well as a EZ-B v4/2 Comm Upgrade kit last month and I am waiting for delivery, however if there is no advantage of using the upgrades with a direct USB to TTL connection, then I can begin working on my bots.
Here’s the link to instructions: http://www.ez-robot.com/Tutorials/Lesson/76
My question was more focused on the hardware. Do I need to do the physical upgrade to my original v4 EZ-Bs to make them EZ-B 4/2 (Comm 1 to Comm 2) ? Is there an advantage?
I did place an order from the world famous EZ-ROBOT.COM website an EZ-B 4/2 and an EZ-B v4/2 Comm Upgrade kit. Looks like I need to order another EZ-B v4/2 Comm Upgrade kit so all three of my EZ-Bs will be rocking.
Thank you.
