Hello everyone, my uConsole’s trackball always gets stuck when moving downward. Sometimes when I try to scroll down, it even goes up instead. Have you encountered a similar issue? Is there a solution?
A lot of people replace the stock trackball with a trackball with this one. Model EVQWJN007

I’ve replaced my 2 uConsoles and the DevTerm when I had one with them. 100% better then the stock one IMO.
Updating the keyboard firmware will also help a bit, or flash the keyboard with the community QMK frimware for the best resaults. Again IMO.
thank you,I will buy IT and replace。
Can flashing community firmware fix a trackball’s malfunction, or only slightly improve it?
Also, a relatively dumb question: how do you flash keyboard firmware?
It will help the stock trackball but a replacement trackball will make the biggest difference.
Here’s the post with the QMK firmware for the uConsole. Use the firmware dated 20240922 it’s 5-6 post down in the thread. Again for best results replace the trackball.
thanks,As someone all thumbs like me, I guess I have no choice but to switch to a trackball.
Do you know of a current source? The link is dead.
the link changes all the time, also depending on location, just search aliexpress for the part number
Thanks, found it! Blackberry trackball!
you may need to order it from different sellers as they are not the same even if they have the same sku
If you have one, you could try the original link with a VPN. It still works for me, just set your location to a different country. That way you can be sure its the right part..
Which country? I have NordVPN
Recently, I had this very same issue.
I have a bottle of alcohol (70%) in spray, purchased at a local drugstore.
I removed the frontplate, picked the trackball, sprayed alcohol on it and started to move it in all directions. It was very wet so I decided left it to dry.
After that, I assembled the uConsole again and the problem was solved.
But it doesn’t hurt to have spare trackballs.
Rex,thank you very much, I replaced the trackball, very smoothly now,that enhanced my sense of happiness。
