Note: R62 and R64 are populated with 0 Ohm resistors by default. In order to use the volt meter, they
will need to be replaced by 1 Ohm resistors.
3 Input/Output Connectors and Pin Usage Table
The following table provides details on which K40X256 pins are using to communicate with the the I/O
interfaces onboard the KwikStik.
Note: Some port pins are used in multiple interfaces on-board and many are potentially connected to
off-board resources via the Primary and Secondary Connectors. Take care to avoid attempted
simultaneous usage of mutually exclusive features.
