This is an open hardware probe for the Serial Wire Debug (SWD) and JTAG protocol. Based on the RP2040 MCU.
The firmware is available here and is open-source: ...
- The 10-pin Cortex-Debug connector is used.
- The programming connector is the Tag Connect TC2030, however for just loading firmware the USB bootloader is recommended.
- Castellated vias for all programming pins, power and 2 GPIOs.
- USB-C connector.
- Target 5V and
Vtargetis protected with an diode circuit to not have current flow from the target to the host. - The probe support 1.8v - 3.3v signal voltage and can track
Vtarget. - The key pin on the Cortex-Debug can be connected to the protected 5V.
The schematic can be found in the GitHub actions, full production files are generated for each commit.
The rs-probe package sold on our shop contains two 10 wire ribbon cables and 4 10p connector.
