Where do i get an ST LINK?
Is it a hard thing to hack with it ?

Thank you

HELLOOOO

Just bought my first ZT3 pro :)))
second hand
It’s in pretty good condition but i would like to do a “full checkup” and preventive maintenance before starting to use it more heavily. I don’t know if this makes sense.
Any advice?
Thank you!!
