Schematic for Meepo V3S Skateboard Lights. Meant to power these 24V WS2811 COB Leds using the Meepo V3S 36V Battery and wled firmware.

This was my first real PCB project, so there were many (easily fixable) issues, but it still works as-is.
- Did not pull EN high (whoops). Bridge the two upper pins of the connector after the board is powered on.
- ESP-Prog connector is mirrored (whoops again).
- The output capacitor I planned to use did not support 24V. There is a capacitor with the same footprint and lower capacitance but higher max voltage that I used instead. Let me know if you want the full BOM.
- There is no power switch. I intented to use an inline waterproof switch on the connector, but it would have been nice to be able to disable the board without unplugging it or pulling the fuse.
- There are no holes (or space for them) to connect it to a mount.
- Level shifter did not work. I just bridged the pins and it works fine.
