Hi DJ,
Would you help to answer my question as below :
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?
EZB4 can support the heavy duty servo (VDC 12V)?
Will it reduce the power if servo ports are full ?
Thanks for your attention.

I am looking for a diagram to follow that highlights the following:
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.
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.

Use a usb camera instead of the ezrobot camera for an embedded system.

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.
You can’t use the camera - as the usb ezb page explains. You lose the camera port when connecting an ezb uart to a pc. This is because the camera port is used by the uart to the pc.
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
First and foremost, I want to thank you for taking time to address my question. I am very grateful. I also realize that I have not articulated my question very well.
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 will need multiple USB ports on the computer or a USB hub, and one USB to TTL adapter per EZ-B. Each one will have its own combination port on the computer, then you just address them by computer port and use their EZ-B number as usual for multiple boards (board 0 is the default and the only one with a movement panel).
You can't chain them together.
