So we don't need the firmware upgrade anymore?


The ezb v4 and ezb iotiny both have firmware. If the firmware is out dated, update the firmware.

I dont understand your question but I attempted to answer it best I could. Also, please never ever double post. Your other post was removed.


my question is simple, I have the new 2019 EZ- builder program


Do I need the  ezb v4  firmware upgrade?

I wish it was that simple:). I’m still unable to understand the question. If your ezb v4 or ezb iotiny have an old firmware on them, you can upgrade them with the respective firmware utilities. However, you only need to upgrade the firmware if there’s a feature that isn’t working - generally very noticable. The controllers ship with the latest firmware. Given the questions you’ve been asking on the forum, I do not recommend using the firmware upgrade utility because I don’t have confidence in the reliability of your windows installation. There’s a high probability you will damage the ezb, even though it’s nearly foolproof:)

Also, there is no 2019 version of EZ-Buulder. You can see the version of your installation in the title bar when the software loads. If there is a new version available, there is a window that will flash notifying you of the new version. An ARC version includes the year, month, day and release, in the format of 2019.03.18.00 for example.

Forget about the ezrobot firmware:)

Hi EZang60, I may be wrong but maybe you're confusing Firmware with Software.

ARC is Software that resides on your computer. It can be upgraded by downloading the latest and greatest "ARC Designer" from the Download Software and simply install it right on your computer. You can find it here: Download Software

Firmware resides on the EZB or iotiny. It's what makes the board run all the devices and communicate with the computer where ARC is running. Usually you shouldn't monkey around with updating this unless you're having problems or know it's an old board. You'll find a program already installed on your Windows 10 computer that will do the Firmware update for you. You'll find it in the Windows Menu (the little window icon in the lower left of your desktop) under Synthiam. Just click on the Firmware Update utility that matches the EZB you have and follow the directions on the screen.

It's been a long time since I used this utility but I think it may tell you if you have the latest version already installed before you actually click on the Update Button to an update. Again, don't do it unless you know you need it or know what you are doing! It's very possible you could trash your unit if something goes wrong. I've seen other users on this forum have this happen. If that happens just throw it in the garbage.


Again, thanks for all your responses
