What is the role of JP3?

Hi,

JP3 allows external debugger to be connected.

Short to disable CMSIS-DAP interface.

Have a great day,

Thanks for your answer。Do I have to short this when not using external debugger?

[soledad]

No, you have to short the JP3 jumper only to allow an external debugger through the J5 connector.

Have a great day,
Sol
