@lupyuen@PINE64 What type of solder did you use? I see rosin splatters and one side that looks nearly perfect. It looks like it was just the solder that failed to perform.
@lupyuen@AmpBenzScientist It has always been somewhat daunting when I have to solder through-hole components. Soldering surface-mount components with paste and hot plate is actually much less stressful. Learning to use kicad was also totally worth it.
