Questions
How big is the Ov twin PCB?
It measures 64 × 64 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Ov twin use?
121 parts, built around the RP2040, W25Q128JVSIQ, LIS3DH and SN74LVC1T45DBV. 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 Ov twin KiCad files?
From the OneVariable/ov-twin repository on GitHub, at the commit this page was made from: the board is ov-twin.kicad_pcb and its schematic ov-twin.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ov twin design in my own project?
Its repository states no licence, so its author keeps all rights: ask OneVariable before reusing the design.
