SAOGNR - An SAO for Morse Code

K6VNI did the soldering challenge at Supercon and was gracious enough to trade me one of his SAOGNRs that he built for one of mine! Twins except for the PCB color. Nice job!

Well, I left Houston with 20 badges and came back with 3 plus 1 that someone had made and gave me! (Photo later). 

I did want to note: if you plug this into the Supercon badge, the volume will be very low. I haven't figured out what's going on, but it is power related. If you turn the badge off and hold BOOTSEL on the badge's main RP2040 (the one on the back of the big badge) and then turn it on, the SAO will sound normally loud (which isn't that loud, to be fair).

I assume both processors going at once is too much for the power system on the badge, although everything works fine, just not enough umph to really make the speaker run.

Thanks to everyone who participated!
