Continuing from the padstack design for the FDN340P this post focuses on the footprint layout. One word of caution, I’m just learning how to create these footprints so it’s likely that there are problems with the footprint. I’m not sure if the silkscreen overlap will be a problem, however I plan on figuring that out sometime down the road.
After expanding a raid the partition and file system will need to be grown to utilize this extra space. The instructions here are tailored for a GPT partition with an XFS filesystem. Continue reading for a complete log of the process.
I’ve been looking through the Arduino schematics in search of a circuit to perform automatic power supply selection in the case that there are two available supplies. I had convinced myself that there was a design flaw in the Arduino Uno selector, however upon further inspection it seems it should work just fine.
