electronics/projects/cederom-adapter-stlink-v3mods/README.mdCeDeROM STLINK-V3MODS ADAPTER
Just a simple adapter for STLINK-V3MODS [1] that provides 2.54mm raster pins connector very popular for prototyping and/or testing automation. Production files (gerber+excellon) and sch+pcb (pdf) are in out/ directory.
This is smallest and cheapest debug probe with JTAG/SWD capabilities, 3..3,6V capable IO with 5V tolerant inputs, Virtual COM Port, but also multipath bridge that provides SPI/UART/I2C/CAN/GPIO (UART with control lines).
Firmware is closed source, unfortunately, and in may need to update firmware in order to get some additional features (i.e. second UART operational) [1].

Questions
How big is the Power toggle on hold off PCB?
It measures 34.8 × 11.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power toggle on hold off use?
25 parts, built around the BSD235C-VB. 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 Power toggle on hold off KiCad files?
From the cederom/CeDeROM-STUFF repository on GitHub, at the commit this page was made from: the board is electronics/projects/cederom-test-power-toggle-on-hold-off/power-toggle-on-hold-off.kicad_pcb and its schematic electronics/projects/cederom-adapter-so24-to-dip24/cederom-adapter-so24-to-dip24.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power toggle on hold off design in my own project?
Its repository states no licence, so its author keeps all rights: ask cederom before reusing the design.
