Raspberry Pi Debug Probe - Plug-and-play, USB to serial-debug & UART, 3-pin debug connector, Multiple debug platform supported

Raspberry Pi Debug Probe is a complete plug-and-play interface debug solution perfect for Raspberry Pi Pico, XIAO RP2040, other RP2040-based microcontrollers, and microprocessor-based platforms. It bridges the USB interface to a dedicated serial debug interface and industry-standard UART interface, both of which use a small, keyed, 3-pin debug connector, published for the next standard.

Feature

• All-in-one Debug Probe: Bridge USB interface to dedicated serial debug interface and industry-standard UART interface
• Plug and Play: Apply a 3-pin debug connector for working with a single unidirectional clock pin and a bidirectional data I/O pin
• Multiple Debug Platforms Supported: Not only Raspberry Pi Pico and RP2040 but also other microcontrollers- and microprocessor-based platforms
• Raspberry Pi Production Quality: Based on the Raspberry Pi Pico hardware design and runs the open-source PicoProbe software

Description

It applies small, keyed, 3-pin debug connectors, which is designed to work with a single unidirectional clock pin and a bidirectional data I/O pin. This arrangement can support ARM’s Serial Wire Debug (SWD) or things like cJTAG, for example.

It bridges the USB interface to a dedicated serial debug interface and industry-standard UART interface. While it has been designed primarily for use with Raspberry Pi debug targets, the Debug Probe provides standard CMSIS-DAP debug and UART interfaces over USB. That is, it can be used to debug other targets, or simply as a cost-effective USB-to-UART cable.

It comes with a kit containing the probe hardware in a plastic case, and a set of cables to cover the vast majority of use cases. Represented as Raspberry Pi quality and its production ecosystem, this is based on the Raspberry Pi Pico hardware design and runs the open-source PicoProbe software.

FAQ

What should I be noticed when I used it?

The UART TX and RX mentioned above are the pins from the target perspective. E.g., if the target is a BCM2711 SoC, then RX means the signal driving into the SoC and TX driving out from the SoC.
