Hello everyone


I want to measure some TTL level signals with oscilloscope therefore I need an output pin on the board I know that there is USER_LED but it's hard to connect ossilloscope on it.


I have seen the connector J15 has JTAG_TDO pin but as far as i know it's not connected to CPU. Is it possible to use it as GPIO ?

Do you know anything else that I can use an an output pin?


Best Regards
