README
_debugger/black_magic_probe/README.mdBlack Magic Probe (BMP) Hardware Adapter
This documentation describes the hardware schematic for configuring an STM32 BlackPill as a Black Magic Probe (BMP) debugger. This design breaks out the essential debug and serial interfaces necessary for flashing and interacting with embedded targets.
Schematic Overview
The schematic details the pin routing from the BlackPill's microcontroller to dedicated external connectors, providing a unified interface for hardware debugging.
Exposed Debug & Serial Interfaces
The following critical signals are exposed for target interaction:
- Serial Wire Debug (SWD):
SWDIOandSWCLK. - JTAG Interface:
TDIandTDO. - UART Bridge:
TXandRXlines for target serial communication. - Control & Power: Target reset (
RST),+3.3V, andGND.
Hardware Connectors
The design organizes these signals into specific pin headers for modular target connections:
- J1: Groups a 3-pin interface, likely designated for the UART bridge or basic target control.
- J2: The primary 4-pin debug header, exposing the SWD/JTAG signaling lines.
- Auxiliary Connectors: Multiple 2-pin connectors utilized for power delivery (
+3.3V,GND) and other localized signal pairs.
Status Indicators
The schematic includes visual indicators to monitor the probe's state during execution:
- D1 (Status LED): Pin
PC14, typically used for general error or operational status indication . - D2 (UART LED): Providesvisual feedback for serial bridge activity (TX/RX traffic).

Questions
How big is the Rp pico bmp probe PCB?
It measures 51.5 × 67.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rp pico bmp probe use?
13 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 Rp pico bmp probe KiCad files?
From the xtarke/iot_zephyr_samples repository on GitHub, at the commit this page was made from: the board is _debugger/black_magic_probe/rp_pico_bmp_probe.kicad_pcb and its schematic _debugger/black_magic_probe/rp_pico_bmp_probe.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rp pico bmp probe design in my own project?
Its repository states no licence, so its author keeps all rights: ask xtarke before reusing the design.
