The cy8ckit 050 Kit (PSoC5 LP) has a lot of pins. Its tricky to know which of them are safe to use. The list below is an overview. A more detailed description is available here (page 56). The Pins connected to Jumpers (J) can be safely used when the Jumper is not set. To make the Voltage reference available, the corresponding pads have to be populated.
This list comes with absolutely no warranty.
