The Particle Debugger brings professional ARM debugging to your bench at a fraction of the cost of full-featured probes. It connects to the standard 2×5 SWD/JTAG port found on Particle boards and other modern ARM microcontroller platforms, letting you program, step through code, trace stacks, and watch memory using open-source tools like GDB.

Beyond the SWD interface, the debugger includes socket headers for power, data, and a bonus UART connection for serial debugging. It supports the open-source CMSIS-DAP specification and DAPLink firmware developed by ARM.

Key Features

• SWD/JTAG Programming – Program and debug ARM chips via the standard 2×5 connector
