This is a test board for STM32C092 microcontroller and CAN bus. It contains the following components, common to most/all standard boards in the DAQ system:
- STM32C092FCP6 microcontroller, TSSOP-20 package with built in FDCAN
- SN65HVD232QDRG4Q1 CAN transceiver
- SST25PF020B-80-4C-SAE SPI flash memory
- Tag-Connect 6-pin programming header through SWD All STM32 peripheral pins and the CAN bus are broken out to headers.

Questions
How big is the BusDebugger PCB?
It measures 111.9 × 39.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BusDebugger use?
48 parts, built around the STM32C092KBT6, SN65HVD232QDRG4Q1, SST25PF020B-80-4C-SAE and AO3400A. 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 BusDebugger KiCad files?
From the joshop/Papyrus-MITRT repository on GitHub, at the commit this page was made from: the board is KiCAD/boards/BusDebugger/BusDebugger.kicad_pcb and its schematic KiCAD/boards/BusDebugger/BusDebugger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BusDebugger design in my own project?
Its repository states no licence, so its author keeps all rights: ask joshop before reusing the design.
