PCB Design(4 Layer) of Breadboard friendly RP2040 Dev Board with USB-C.
Layer 1: Front Cu
Layer 2: Gnd
Layer 3: Gnd
Layer 4: Back Cu
Initially my designs had inner layers as gnd and 3.3V, I got some netlist parity when I uploaded to my PCB manufacturer. But KiCad wasn't showing any errors in DRC, So I made both layers as Gnd.
All components were purchased in lcsc.com except RP2040, Which I purchased locally for 80Rs(~$1)/μC from robu.in.

I got my PCBs manufactured from Aisler.
Rev2 has lot of inspiration from michael rangen's PCB layout. Also I've used KiBuzzard for silkscreen texts, Which I personally like very much.
