[bouLED] Drawing the main board’s schematics

Today, I started drawing the main board’s schematics. It’s not finished yet: the decoupling capacitors have yet to be chosen and I’m not done with the STM32H7 (pins like VBAT, VREF, BOOT0, etc.). As a teaser, here’s the power supply:

It takes a 14.80V input (from a 4S LiPo) and steps it down to 3.3V. That’s not the right buck converter (it should be a LT1765-3.3), but the pinout is the same, so when it’s done I’ll only have to change U1. The SDHDN_n pin is left floating on purpose, according to the datasheet.

Here’s a sneak peek at the unfinished parts of the schematic:
