Overview
Flex debug cable is an open-source printed circuit board by PicoballoonLabs, from the PicoballoonLabs/Debug-Boards repository on GitHub, published under the MIT licence. It is a 2-layer board of 100 × 5.5 mm with 3 parts on 9 nets, routed with 39 tracks and 11 vias.
It is built around the GT-B0353FSV06-08B0201. It belongs with the radio and wireless and sensors and measurement boards of this library.

README.mdDebug-Boards
This repository contains the hardware designs for our integrated debug probe, debug adapter, flex debug cables and RF calibration board.
📦 Contents
This repository includes designs for:
- Flex debug cable: Flexible flat cable that connects a debugger to the low-profile debug connector on the target board.
- Debug Adapter: SWD debug adapter board that breaks the target debug connector out to a standard debug host, with its own target power supply.
- Integrated Debugger: Integrated debug probe for flashing and debugging target hardware over SWD, with a UART bridge and switchable target power. It is hardware compatible with the Black Magic Debug firmware.
- RF VNA calibrator: Calibration board for vector network analyzer (VNA) RF measurements.
Each subdirectory is a standalone KiCad project with its schematics and PCB layout, and a production folder with the manufacturing files (gerbers, BOM, pick-and-place positions) of the released revisions.
The projects use the symbol, footprint and 3D model libraries from Hardware-Resources.
🔌 Integrated Debugger firmware
No firmware is distributed in this repository. The Integrated Debugger runs the upstream Black Magic Debug firmware (GPLv3), which can be installed and updated with bmputil.
The hardware designs in this repository are original work, released under the MIT Licence (see LICENSE). They are compatible with Black Magic Debug firmware but are not derived from it.
📄 Licence

Questions
How big is the Flex debug cable PCB?
It measures 100 × 5.5 mm and has 2 copper layers, 0.17 mm thick.
What parts does the Flex debug cable use?
3 parts, built around the GT-B0353FSV06-08B0201. 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 Flex debug cable KiCad files?
From the PicoballoonLabs/Debug-Boards repository on GitHub, at the commit this page was made from: the board is Flex debug cable/Flex debug cable.kicad_pcb and its schematic Debug Adapter/Debug Adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Flex debug cable 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).
