Features: The Debug Probe debugger is equipped with the RP2040 microcontroller chip independently developed by or for RPi For RPi Debug Probe is an official USB hardware debugging downloader designed specifically for Picos, produced by RPi Adopting an integrated design with weldingfree and plug play features, it can be connected to the debugging interfaces of the targeted board through SWD interfaces for debugging Equipped with the RP2040 microcontroller chip independently designed by For RPI, the onboards MicroUSB interfaces is used to connect PC hosts or other mainboard onboards 3PINSWD interfaces, and to connect the targeted board onboards 3PINUART interfaces being debugged. It can be used to achieve the standard CMSIS-DAP interfaces for USB serial port adapters Can be used to debug most ARM based microcontrollers, suitable for OpenOCD and other debugging tools that support CMSIS-DAP Adopting the same type of 3PIN debugging interfaces specification as for RPi, equipped with good quality clear plastic cover and related connection cable programs open source, upgrading firmware is more convenient Specifications: Size:approx 3.2x2.2cm/1.26x0.87in Item:Usb Serial Port Downloader UART Burners For RPi Debug Probe Debugger Interfaces: Micro USB Main frequency: RP2040 Microcontroller Chip Compatible the CMSIS-DAP standard Works with OpenOCD and other tools Package Types: Debugger Only /Debugger with Breadboard Note: Due to the problems of lighting effects and shooting angles, there will be certain tolerances in the product, please understand. Please allow 0-1cm error due to the manual measurme Package includes: 1Set Debugger Probe
