Started routing PCB
I started to route the PCB on my Devboard, currently I have all of the GPIO pins routed, the USB-C routed, the crystal routed, the buttons, and the LED. All I have left really to route is GND, 3v3, 1v1, and run. I also changed up the layout abit.

PCB LAYOUT V1
I made footprints for every single part and started working on a layout for PCB, Currently I'm trying to get an efficient design that also looks pretty good. currently I'm not too happy with this layout and want to make it more symmetrical and fix up some of that silkscreen.

Fixed Schematic
Well turns out I had a few errors in the schematic and even a short circuit!!! I used some power flags to satisfy ERC when it was buggin, and I spent a while pulling at my hair trying to figure out what's wrong with it, but it's all good now.

Finished Schematic V2
Well Schematic V1 was lowk very boring imo so I locked in and added more components and upgraded some other ones like the voltage regulator so the board can now handle 0.6 amps instead of the old 0.25 amps. I added a BOOTSEL button so flashing firmware will be easier. I also added a NEOPIXEL status LED as seeing your boards status is always nice. I will prolly start working on the PCB now...

Made Schematic V1
Made the V1 schematic for my Devboard. Currently it has USB-C power, I might add in battery charging. This Devboard currently features a RP2040 with a 16 Mb flash storage, a reset button, and a LED to indicate power in the board. I'm currently pondering what sensors I might be able to add to the board.
