This project contains the hardware designs for a RP2040 based CMSIS-DAP debugger running the free-dap firmware.
This project is build with atopile.
- USB interface (data and power)
- status LEDs for VCP (Virtual COM Port), DAP status, and power.
- level shifted target interface (SWD, UART)
- 1.2-5.5V target logic voltage
There are various layouts and standalone boards available:
 |
 |
|---|---|
| Basic layout without connectors (for inclusion in your own design/PCBA) | Standalone stick shaped layout with female USB Type-C, Cortex-M debug header and 4-pin JST-SH UART connector. All inside a PCB enclosure. |
 |
 |
| Standalone RPDAP Compact board (JLink Base Compact compatible board shape) | JLink Base Compact compatible "footprint" (for using as build-in debugger/programmer) |
The firmware for the debugger is available in the free-dap repository. Follow this standard RP2040 flashing procedure to flash the firmware.
This RPDAP Stick has a build in enclosure in the design (part of the PCB), and the RPDAP Compact board has a 3D printable enclosure available.
