The version-dongle is a USB dongle with the STM32G431CBT6, inspired from the nRF dongle. This is an experimental project.
The dongle has USB-A fingers, 1.2mm PCB with a 0.8mm case, adding up to 2mm, to save PCB costs. It also has castellated holes, making it a compact devboard.
The dongle has support for many GPIOs, mapped to various function picked from the official datasheet from ST.

Questions
How big is the Version dongle PCB?
It measures 18 × 50 mm and has 2 copper layers, 1.2 mm thick.
What parts does the Version dongle use?
26 parts, built around the PRTR5V0U2X. 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 Version dongle KiCad files?
From the NeerajR18/version-dongle repository on GitHub, at the commit this page was made from: the board is PCB/version-dongle.kicad_pcb and its schematic PCB/version-dongle.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Version dongle design in my own project?
Its repository states no licence, so its author keeps all rights: ask NeerajR18 before reusing the design.
