@Merne... Sorry to hear that... I have 8 ezbs... with the exception of a port failure on one of them all have been rock solid so far...

When you mean stop talking, maybe it is just the speaker (contacts)?... Does it function normally otherwise? If it is just a sound problem you can remove the back of the ezb and access the speaker. From there you might be able to adjust the speaker contacts to get you sound back...

*** EDIT*** sorry re-read your post... so it's not just the sound... Does the leds flash? If it is completely dead, have you checked the main fuse?...

If the ezb was overloaded the onboard polyfuse will need time to reset before the ezb functions properly again...

Hi Richard, The lED's flash on boot up and I get a blue flash and I can connect to the Wifi from my computer and I get an IP address so my laptop says. I can not connect with EZ-Windows. I do not believe I have over loaded the EZB. I am just using one port testing my servos. on a 6VDC SLA battery.

I have tried the reset button several time, no luck.

How long do you have to wait for the onboard polyfuse to reset if that is the issue, not sure.

I have other EZB's and am very happy with them. If it was just the one EZB I RMAed it would be a fluke, but two, I get frustrated.

Thanks

Is your other ezb (the good one) in WP or Client mode? Check the speaker anyway, it's possible the no sound and inability to connect might be 2 separate problems...

Sorry to say that you are obviously doing something to damage the ez-b. Can you be more specific on what you are connecting to it so we can help prevent this from happening?

If you're using the EZ-B for Revolution robots - then operation is pretty self explanatory in the LEARN section.

If you are building a robot from scratch and connecting your own motors and devices to it, you can easily damage the EZ-B by connecting something incorrectly.

Tell us about your wire schematic on your custom robot and we can help prevent damaging more ezbs

Under the plastic shell of the EZ-B is a PCB. The pins of the EZ-B are connected to an ARM microcontroller. If incorrect voltage is applied to the pins, or the pins are shorted, you will damaged the EZ-B... As you are experiencing.

My working EZBs are in AP Mode and work fine. I have checked the speaker and the 2 springs are connected to the gold dots on the board. I have also used different power supply's not luck. Also, when I scan for IP's it never find one using EZ-windows "connect button" Even though I go to status in my Wifi and it says the IP of 192.168.1.1

I wish it was that easy to fix, I am afraid I will have to ship it back for an RMA.

Again, please explain what you are connecting to your EZ-B by providing either one of these two answers

1. Which EZ-Robot Revolution are you connecting? (Six, JD, Roli)

2. If this is a custom robot, please provide a schematic.

The EZ-B does not simply "fail", much like your phone processor does not just "fail" - or your PC processor just "fail". It has something to do with what is connected... Specifically since you claim to have two failed. The processor in the EZ-B is a genuine STM32 ARM processor. If it is overloaded or shorted, the processor will be damaged - as what you are experiencing.

Please provide details on what Revolution Robot you are using -or- a schematic of your custom robot.

DJ, I am using standard servo, nothing special, MG996R's. Connecting the 3 pins to the board, black to black, red to red, white to white. The servos are pre wired. I am not miss using the EZB. Like I said I am using a 6VDC SLA battery.

What I was doing is disconnecting the EZB several times when I was not calibrating the servos I am using. This should not cause issues.

Way am I not having issues with my other EZBs? Doing the same thing with them and they work fine. Except I have 30 servos connected and using 2 boards.

I am building a second Inmoov, like my first.
