::: info
The PX4 node ID can be configured using the [UAVCAN_NODE_ID](../advanced_config/parameter_reference.md#UAVCAN_NODE_ID) parameter.
The parameter is set to 1 by default.
Devices running the [PX4 DroneCAN firmware](px4_cannode_fw.md) (such as [ARK CANnode](ark_cannode.md)) can use the
[CANNODE_NODE_ID](../advanced_config/parameter_reference.md#CANNODE_NODE_ID) parameter to set a static node ID.
Set it to 0 (default) for dynamic allocation, or to a value between 1-127 to use a specific static node ID.

Common CANNODE parameters that you can configure include:
- [CANNODE_NODE_ID](../advanced_config/parameter_reference.md#CANNODE_NODE_ID): Set a static node ID (1-127) or use 0 for dynamic allocation. See [PX4 DroneCAN Firmware > Static Node ID](px4_cannode_fw.md#static-node-id) for more information.
- [CANNODE_TERM](../advanced_config/parameter_reference.md#CANNODE_TERM): Enable CAN bus termination on the last node in the bus.
## Device Specific Setup
Most DroneCAN nodes require no further setup, unless specifically noted in their device-specific documentation.
