I just fried my Renegade.
I was working on setting up my Renegade, when a metal screwdriver that was sitting on the workbench came in contact with the far-corner pins on the GPIO (near the IR sensor). It was very brief, just a fraction of a second, and poof – the Renegade was dead.
At first, I thought the 5V pin had shorted to GND, but I think it’s more likely that 5V shorted to 3V3 since those two are right next to each other at the end.
I noticed the other corner of the board near the USB jack was warm, so I initially thought maybe there was a self-resetting fuse there that needed to cool off, and I’d be back in business after a few minutes. Nope. I pointed my FLIR camera on the board and saw a bright glow where the RK805-1 power management IC is.
I understand that the GPIO pinout basically follows the “standard” Raspberry Pi pinout, so this might be a possible problem for all SBCs like this and not just the Renegade.
So this isn’t a request for support, exactly, just an announcement to others to be careful and pay attention to the area around your SBCs, and to alert that it’s VERY easy to fry your Renegade if anything conductive comes near the edge of the GPIO header.
I think I can replace the RK805-1 PMIC so that I don’t have to throw this otherwise brand-new Renegade in the trash, but so far the only place I’ve been able to find that IC is on AliExpress. Do the folks at Libre have a way for me to get that part?
