Digital SideCar
From FRC:Wiki
The digital sidecar connects to the digital I/O module in the cRIO. It sports 10 PWM outputs, 14 GPIO ports (5V TTL Digital Input/Output ports), an SPI interface, and eight relay outputs.
[edit] Connection Between the Digital SideCar and the cRIO
The connector the cable has is a DB37 connector. Some teams have made their own ribbon cables because the provided ones are very stiff. Whether or not the rules will allow for this has yet to be seen.
