# Southbound Drivers

Southbound drivers collect device data by protocol. Northbound applications send data to a cloud platform or processing engine. You need at least one of each for protocol conversion.

For the generic setup steps, see [Create a Southbound Driver](../../configuration/south-devices/south-devices.md). For custom development, see the [SDK Tutorial](../../dev-guide/sdk-tutorial/sdk-tutorial.md).
