Just like Raspberry Pi, Revolution Pi also comes with GPIO pins. GPIO is an interface that transfers signals that, for example, are picked up from a sensor to the control unit. The interface has 28 individual pins from which, depending on the model, you can use 14 and 16 respectively to read and send out signals. The GPIO’s are not, like on Raspberry Pi, directly usable on the RevPi Core as the architecture is not suitable for use in an industrial environment. We therefore offer IO modules in a separate housing. You can simply connect the IO modules with the PiBridge using your RevPi Core.
Our current IO module range includes:
| Product | Available inputs | Available outputs |
|---|---|---|
| RevPi DIO | 14 | 14 |
| RevPi DI | 16 | – |
| RevPi DO | – | 16 |
The pins are occupied as follows:
| Pin | DIO | DI | DO |
|---|---|---|---|
| 1 | IN1 | IN1 | – |
| 2 | IN2 | IN2 | – |
| 3 | IN3 | IN3 | – |
| 4 | IN4 | IN4 | – |
| 5 | IN5 | IN5 | – |
| 6 | IN6 | IN6 | – |
| 7 | IN7 | IN7 | – |
| 8 | IN8 | IN8 | – |
| 9 | IN9 | IN9 | – |
| 10 | IN10 | IN10 | – |
| 11 | IN11 | IN11 | – |
| 12 | IN12 | IN12 | – |
| 13 | IN13 | IN13 | OUT15 |
