README
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.

Questions
How big is the Integrated Debugger PCB?
It measures 36.8 × 16.4 mm and has 6 copper layers, 1.07 mm thick.
What parts does the Integrated Debugger use?
72 parts, built around the STM32F103CBU6, TPS22916CNLYFPR, MAX40200ANS+T and TLV76733DRVR. 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 Integrated Debugger KiCad files?
From the PicoballoonLabs/Debug-Boards repository on GitHub, at the commit this page was made from: the board is Integrated Debugger/Integrated Debugger.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 Integrated Debugger 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).
