This is the minimal RP2040 board from the RP2040 Hardware Design Guide made with tscircuit
The design is slightly updated to use a USB-C port.
This is all in the PDF, but for lazy readers here's what the original design looks like in 3D, the schematic and PCB. Please check out the PDF if you're working on this because it has a much better breakdown of each part of the schematic.
