In order to build the *.uf2 file, which then can be transferred to the RP2040 by copying it to the virtual disk:
mkdir build
cd build
cmake ..The file will be called main.uf2.
sudo src/openocd -s tcl -f interface/cmsis-dap.cfg -f target/rp2040.cfg -c "adapter speed 5000"

Questions
How big is the Powerbank devboard PCB?
It measures 100 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Powerbank devboard use?
185 parts, built around the RP2040, W25Q128JVSIQ, BQ40Z80RSMR and TPD6S300ARUK. 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 Powerbank devboard KiCad files?
From the math-milan/PowerbankTestCode repository on GitHub, at the commit this page was made from: the board is pcb/Rev0.1/powerbank_devboard.kicad_pcb and its schematic pcb/Rev0.1/bms.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Powerbank devboard design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
