Help with quokkadb Community edition
Posted by: Astro13 on 2025-07-03 16:52:41 So, Using the schematics, I had a PCB built for a quokkadb (https://github.com/rabbitholecomputing/QuokkADB-community-edition-kicad) and it seems to be fine. I have soldered everything to it, but the one issue is that it doesn't work. The Pi won't do any sort of blinking with the Quokkadb firmware (https://github.com/rabbitholecomputing/QuokkADB-firmware?tab=readme-ov-file), but the Pi does work with some other stuff. The LED on the board does nothing, and it refuses to interact with the mac (1990 mac classic). The only thing I have gotten it to do is power my mouse when the USB is connected to the pi. Help. I have attached my UF2 file and an image of my board.

Posted by: zigzagjoe on 2025-07-09 07:44:10 No offense intended, but what can be seen of the soldering there looks rough on the SMD components. You will want to double check everything: verify values, orientations & polarities, and make sure there aren't unintentional bridges or missed connections. Additional flux and removal of any surplus solder is also a good idea.
