I am a college student from Taiwan. I bought the board MKT564L144S1M for my project.
While i used it for the first time, I found that the Mini-MODULE fails to convert the voltage to 3.3V for the usage for SPC5643L. I consider the J4 jumper as the jumper for converting the voltage for SPC5643L. If that's right, then the voltage output after 1+2 should be 3.3V. But the output was 12V ,which makes the temperature of SPC5643L extremely high. So is there a problem with the MINI-MODULE?
