I tried to keep it as stock as possible, but with the added size of the USB-C the length got extended a bit for soldering the connector supports
Decoupling Caps
The decoupling caps are on the bottom side of the RP2040 so a cutout is needed if you are placing this as a SMD component. This shouldnet affect breadboard usage though. I used a different low power DC regulator but it shouldent affect its usability.
Original Pico
There is no 0201 components in the design compared to the original RPI Pico.

You can make an integrated library and use the components for your own design, or download my Altium component library from my github. I post updates regulary

RP2040 is expected to be released in Q2 2021 :)
