So the first Serpano stream happened yesterday, with a bit of a rocky start and my multimeter battery dying, we prevailed and got first first part soldered!

The board offers 3 ways to power it, USB PD, LiPo battery, and DC Jack, I soldered the USB connector and the PD chip as well as the DC Jack, fuse and power switch. Then I soldered the first part of the power path, the DC boost, which converts whatever input voltage we have to 15V, and as you can see in the next photo, it works! I tested with 5V in from USB and 12V in from DC Jack and we get a nice 15.1V (as expected).

On the next stream we will solder the 3x DC buck so we can get 3.3V (for powering most of the system), 5V (for battery charging), and the adjustable voltage used on the power rails.

Stay tuned!
