Is there a list somewhere of the boards that are now coming with the PKOB4 (which is a pickit4 "on board")?
There are two obvious advantages.
the PKOB3 has always been well.. awful. (other words come to mind though), supposedly the PKOB4 will have more or less the same hardware and firmware as the PK4, with all the improvements in programming and debugging speed.
Also, the PKOB4 enumerates a companion virtual com port too that may come in handy.
Yes, one can (almost) always connect an external debugger but i believe one cable instead of three is usually better. (why three? 1)power 2)debugger 3)com port)) Known Devboards with PKOB4
