3.11.2  LQFP144 I/O extension interface 

The I/Os of AT-START-F435 microcontroller can be connected to external devices through 

extension interfaces J1 and J2. All I/Os on the AT32F435ZMT7 are available on these extension 

interfaces. J1 and J2 can also be measured with oscilloscope, logic analyzer or voltmeter probe.
