Power connector in 1.2 is a bit precarious #1

Open reinauer opened 3 years ago

reinauer commented 3 years ago

I got the AmigaStore version of 1.2 and I died about 1000 deaths yesterday when I did a mainboard + daughterboard move and my machine would not turn on anymore. Turns out the power adapter is really close to the metal rail holding the daughterboard in place (and in my case, shorting it). See photos. I fixed it with kapton tape, but maybe it's possible to move the connector in future versions?

Yeah, I have the same issue. If the power connector could be moved down, it would be ideal. The metal rail shorts against the power connector (both front and back)

oh! I see! will change it and upload the version! thanks for the update, for the current version you could solder 4 cables with a male connector to connect later to the PS.

Thanks for the feedback :)

Yep, I just had the 12v line on one go up in smoke due to not spotting this problem after installing it.

sorry to hear that, i've updated the readme.md regarding this, it's actually not required, and as I comment, should be isolated.

Yup, had thought I reported this at the beginning. I dont use this connector and leave it off on the builds I do.
