2.4 User I/O
2.4.1 User Push Buttons
The Carrier provides 4 user GPIO push buttons to the Zynq-7000 AP SoC.. Pull-down
resistors provide a known low default state. Pushing a button connects to VCCio_35 to
assert a logic high.

2.4.2 User LEDs
The Carrier has 8 user LEDs. A logic high from the Zynq-7000 AP SoC I/O turns the
LED on. LED’s are sourced from VCCio_34, banks through current limiting resistors.
*Note, if VCCio_34 is set to 1.8V, the LED intensity will be noticeably lower than when
VCCio_34 is set to 3.3V.
