The Black Magic Probe V2.1 is a next-generation JTAG/SWD debugging tool for ARM Cortex microprocessors. Unlike traditional debug dongles, it doesn't require OpenOCD or STLink — the probe itself is a GDB server, emulated through USB serial. Simply connect via GDB and start debugging directly.

It also includes a bonus TTL-level USB-serial adapter with socket headers for dual GDB + printf debugging. The Black Magic Probe is fully open-source hardware, and your purchase supports ongoing development.

Key Features

• Built-In GDB Server – No OpenOCD or special PC software required
• SWD & JTAG Support – Both debug interfaces on one probe
• 1.7V to 5V Target Support – Wide voltage range for diverse targets
• 3.3V Target Power – Can supply up to 100mA to the target
• TTL Serial Interface – Built-in USB-serial adapter for printf debugging
• Semihosting Support – Redirect target I/O to the host
• Cross-Platform – Works on Linux, Mac, and Windows
• IDE Compatible – Eclipse and other IDEs supported
