[DSP-10] Starting the kit and SMT soldering

[Bob Larkin]

Chris, looks like you are off to a roaring start! With a fillet, you can
inspect the connection. The point where the solder connects to the land is
obvious. With a buldge, it gets covered. There are plenty of good buldging
connections out there, of course!

Good luck with getting it on the air!
