Summary:
Raspberry rp2040 microcontroller gpio 0-25 broken out, gpio26-29/adc0-3 also broken out
similar pinout as raspberry pi pico, but with the gpio 25 broken out, trading a ground pin for a gpio
power pins moved to the top right of the board in a group, both vbus and 3v3

Questions
How big is the Devboard PCB?
It measures 21 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Devboard use?
33 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 cubit010/devboard repository on GitHub, at the commit this page was made from: the board is Devboard.kicad_pcb and its schematic 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 cubit010 before reusing the design.
