My first board for the newly designed radio rocket version 4 came in. I had the surface mount bits fabbed up by JLCPCB, and just did the through-hole soldering by hand.

Since this is often in the rocket when you power it up, you can't tell if its running or not, so version 3 of the rocket played a Rick-Roll when booting up, but for version 4 the 12yo wanted mario.

The Piezo you hear is a small, square, surface mount one, that is actually underneath the postage stamp sized micro-controller.
