RP2040-MicroProbe Project

The RP2040-MicroProbe project aims to create smaller version of RP2040-DebugProbe.

RP2040-MicroProbe Board

The RP2040-MicroProbe board is a 4-layer design intended to accommodate the popular Raspberry Pi RP2040 MCU with all required component to function identically to Raspberry Pi Debug Probe.

This board features target JTAG connector and PC host micro-USB connector. It also has a SWD connector and UART connector for the main MCU debugging. The board is pin-compatible with Raspberry Pi Debug Probe and can be used with the same picoprobe SW.

Preview:

You can view the Schematics in PDF format for detailed information.

STEP 3D file is available with pins.

Features:

• Very small form-factor of about 40x18mm.
• Raspberry Pi RP2040 MCU as a heart of the board.
• 2x5 1.27mm JTAG connector for programming and debugging.
• 1x8 2.54mm SWD/UART/Power connector for programming and debugging.
• Micro USB connector for power and communication.
• Several LEDs to indicate power and status.
• Castellated holes connector for main MCU debugging.
• BOOTSEL button to enter the bootloader mode for flashing new picoprobe SW.
• Pin-compatible with Raspberry Pi Debug Probe.
• Extra TARGET_RESET line connected to GPIO10 for target MCU reset over JTAG.
• Flat bottom side for easy mounting as a daughter board.

CAM files, as well as the BOM and CPL files for JLCPCB, are available.
