README

README.md

Welcome to RedCuttle.

This project is the hardware and software for a JTAG/SWD/UART port multiplexer and switcher.

This hardware allows the control of multiple debuggers and targets to be connected to one another for development and testing purposes. The original motivation for this is the Hardware In The Loop testing of the Black Magic Debug firmware on Black Magic Probe hardware.

Questions

How big is the Testrack breakout PCB?

It measures 40 × 78 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Testrack breakout use?

16 parts. 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 Testrack breakout KiCad files?

From the esden/redcuttle repository on GitHub, at the commit this page was made from: the board is altium_import/testrack_breakout/testrack_breakout.kicad_pcb and its schematic altium_import/testrack_backplane_passive_5u/slot.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Testrack breakout design in my own project?

Its repository states no licence, so its author keeps all rights: ask esden before reusing the design.
