Debug Support
As mentioned above, TP1 and TP7 can be used to connect an external power to
supply VCCIN and V_BCKP and to measure the supply voltage and current.
TP3 and TP5 are used for internal debugging
J1 is used for MMCX connection. After soldering the MMCX connector, it can be
used to measure the PPS signals.
J2, J3, J6 and J7 are debug ports. Connect the signal that needs to be tested to the
square hole and test the round hole, or connect the round hole to a measuring
instrument. Using these debug ports can avoid damage to the PCB pads and traces,
which is convenient for debugging.
