The lines for the digital inputs and outputs on the roboRIO are not limited to those on the DIO port. Multiple ports contain DIO lines and use different voltages. The following table lists the voltages on the DIO lines for different ports.
| Voltage | Ports |
|---|---|
| 3.3 V | DIO, I2C, SPI, and MXP |
| 5 V | PWM and RELAY |
