To use an IDE instead, see the instructions for or . See the for more advanced debug options.
The is an inexpensive and popular SWD debug probe. The probe's connector pinout looks like the image below (connect to this using an ARM 10-pin mini connector like ).
The pin mapping to connect the J-Link Edu Mini to is shown below.
