Overview
DevBoard is an open-source printed circuit board by AaradhyaBarnwal, from the AaradhyaBarnwal/MountPico repository on GitHub. It is a 2-layer board of 26.6 × 51 mm with 38 parts on 54 nets, routed with 599 tracks and 44 vias.
It is built around the RP2040 and W25Q128JVSIQ. Its parts include 16 capacitors, 8 resistors, 6 connectors, 3 ICs and 1 diode. It belongs with the microcontroller boards boards and the RP2040 boards of this library.

I have created a custom RP2040 development board with awesome graphics and two header for each GPIO pins. I took inspiration from "Nimsdai", created a mountain graphics with Nimsdai's famous quote "Giving up is not in the blood" on one side and a rocket travelling across space on the other side. I also added 2 header pins for each pin, so it will be easier to check the signals and connect two components to the same pin at the same time. Why have I design this? Why not? It looks cool! and I learnt some of KiCad on the go.

Questions
How big is the DevBoard PCB?
It measures 26.6 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DevBoard use?
38 parts, built around the RP2040 and W25Q128JVSIQ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the DevBoard KiCad files?
From the AaradhyaBarnwal/MountPico repository on GitHub, at the commit this page was made from: the board is PCD_files/DevBoard.kicad_pcb and its schematic PCD_files/DevBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DevBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask AaradhyaBarnwal before reusing the design.
