Overview
Devboard is an open-source printed circuit board by aethern1k4-stack, from the aethern1k4-stack/XIAO-recreation repository on GitHub. It is a 4-layer board of 17.8 × 21 mm with 71 parts on 85 nets, routed with 789 tracks and 152 vias.
It is built around the NRF52840-QFAA-R, LSM6DS3TR-C and MSM261D3526H1CPM. Its parts include 28 capacitors, 17 resistors, 5 ICs, 2 connectors and 2 crystals. It belongs with the microcontroller boards boards and the nRF52 and nRF5x boards of this library.

README
README.mdXIAO-recreation
My motivation for this project was to originally learn the basics of making dedicated boards with microcontrollers as a starting point into this process of designing and making hardware projects. I aimed to learn how to place things ona board how to route the things and the need for everything ona board to be placed where they have to be placed and how to design things from scratch.
The Kicad file contains an exact recreation of the XIAO nrf 52840 board to the micrometer.
In addition to the page 1 contains a basic rp2040 that is untraced on pcb.
On the second page there is an attempted nice!nanov2 recreation which remains yet to be tested.
The nice!nanov2 recreation prototype in the second page requires a trace antenna.
Feel free to use the files as you see fit and just credit the original person.
The gerbers are also provided in the production files section of this repo.
Kicad files are in the base file folder.
Bootloader to be used is undecided BUT will likely be made to run ZEPHYR RTOS.

Should be noted that this recreation uses all of XIAO's orignal footprints and symbols AND USE ALL EXACT SAME PHYSICAL COMPONENT PACKAGES TO FUNCTION.
In addition to this the parts like PDM microphone and other uneccesary components can be added later.

Questions
How big is the Devboard PCB?
It measures 17.8 × 21 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Devboard use?
71 parts, built around the NRF52840-QFAA-R, LSM6DS3TR-C and MSM261D3526H1CPM. 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 aethern1k4-stack/XIAO-recreation repository on GitHub, at the commit this page was made from: the board is KICAD PCB Files/Secondary fileset/Devboard.kicad_pcb and its schematic KICAD PCB 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 aethern1k4-stack before reusing the design.
