Well that wasn’t fun. To fix a loose connection on the buried I2C line on the board I’m building ended up desoldering a bunch of SPI lines and power lines. But hopefully when this is back together things will work better. Plus I’m getting better at soldering.
It’s amazing how quickly electronics can get really complicated messes of wire, even when primarily using “simple” interfaces and integrated chips instead of discrete components.
Plus I got to get better at thinking out board layout and stop adding extra components after the fact.
