Raspberry Pi Debug Probe

Added to your shopping cart

The Raspberry Pi Debug Probe is an inexpensive, all-in-one USB to serial debug and UART bridge. It provides the necessary hardware and cabling to support “plug and play” debugging of Raspberry Pi Pico and other microcontroller and microprocessor-based platforms.

The Raspberry Pi Debug Probe provides both a processor serial debug interface (by default this is the ARM Serial Wire Debug interface) and an industry-standard UART interface. Both interfaces use a 3-pin debug connector, as specified in the Raspberry Pi 3-pin debug connector specification.

  • USB to two-wire serial debug
    • Arm CMSIS-DAP Serial Wire Debug supported by default
  • USB to UART bridge
  • Works with OpenOCD
  • Open source, easily upgradeable firmware
  • USB power cable and three debug cables included
  • 3.3V nominal I/O voltage
  • Follows the Raspberry Pi 3-pin Debug Specification

Raspberry Pi Debug Probe Product Help and Resources

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

Works well with GDB

I've never been a fan of debugging Arduino projects. You're essentially limited to print statements over serial or blinking LEDs. The pico/probe solve that. You can build everything with gcc/cmake and attach using GDB. It makes it really easy to identify troublesome bugs that sometimes pop up quickly and crash before serial print statements get flushed.

Very useful at a great price!

So far I've only used this Debug Probe to provide a serial console which allows me to see exceptions when my kernel code misbehaves. This works really well and I appreciate the fact that the board has a protective plastic case. The low price is nice, especially considering the high quality of the components in the kit.

Works Great!

I realize that you can make a debug probe from a Pico board, and I have one already. I just liked that this one is smaller, has a case for protection, and comes with a set of all the appropriate cables to connect to a variety of systems to be debugged. It was plug-and-play with my existing VS code development environment. Highly recommended!
