I have tested my team’s robot for a few hours on tile at home, but when taken to the school for driver’s practice on an actual field, motors started to go out. Within a half-hour of practice on the field, two motors stopped working and they would only blink red. I did some research on the forum and …

These’ll help: [image] Two Dead Ports In 1 Day VEX V5 Technical Support Sorry, that you keep losing V5 ports to ESD. Unfortunately, this is a known problem . The best method to prevent further port losses is to apply Antistatic Spray: If you don’t have access to the spr…

Also, if using custom cables: [image] Ports on Brain not working VEX V5 Technical Support As someone who has been crimping Category cable since well before V5 was released, only recently did I finally have the chance to try crimping V5 cables. What I can say beyond a sha…

Thanks for the reply, will look at those.

As said above, make sure cables are properly crimped and use anti-static spray. I’d also like to add to shorten the cables as much as you can, and to eliminate as many sources of static as you can (For example, 3d printers running). I also found that a humidifier works well for dry rooms, but make …

When you are crimping mark sure the wires are in the same orientation between connectors. For example if the yellow wire is on the left side of one end connector, then you need to make sure the yellow wire is also on the left side of the opposite connector.

Static static static, been disconnecting cortex’s and now disconecting V5 get lots of antistatic and apply to and around robot wheels before match

[image] SaltyCB: Static static static, been disconnecting cortex’s The Cortex did not have any widespread disconnection issues related to ESD and generally had no ESD-related issues at all except when using IMEs. When using IMEs, sometimes the user processor would crash or the IME count(s) wo…

Coming back to this thread because my mentor, who has a degree in electrical engineering, has a theory. She currently believes that, since the ports are connected in series, breaking one port damages others. The damaged ports then become more likely to fail. With that theory, i’d suggest moving you…

[image] wewered: the ports are connected in series Please explain how the ports are connected in series. [image] wewered: With that theory, i’d suggest moving your wires as far from broken ports as possible to prevent more from breaking. Even if the ports are connected in series, I fa…

[image] The ports on the V5 brain are separated into 4 quadrants. My mentor believes the ports in each quadrant are connected, similar to how the cortex was. Moving ports away from broken ones (and into a different quadrant) will move them away from any ports that were damaged around a dead port. A…

How to prevent Vex V5 Broken Ports?

You can see images of the internals in this thread:

it looks to me the quadrants are really just b/c of the connectors.
