KDE CAN ESCs¶
KDECAN ESCs are high-end ESCs that allow control and feedback using a custom CAN protocol
Support for these ESCs is included in Copter-4.0 (and higher), Plane-3.10 (and higher) and Rover-3.5 (and higher)
Where To Buy¶
Connection and Configuration¶
- ESCs should be daisy chained together using the KDECAN Wire Kit. One 4-pin CAN cable should be connected to the autopilot’s CAN port. The CAN terminator (the 4-pin connector with a black loop) should be connected to the last ESC in the chain
If using a Cube autopilot, the CAN1 and CAN2 labels are reversed. These instructions assume the ESCs are connected to the CAN1 port which is labelled “CAN2” on Cube autopilots
Logging and Reporting¶
KDECAN ESCs provide information back to the autopilot which is recorded in the autopilot’s onboard log’s ESCn messages and can be viewed in any ArduPilot compatible log viewer. This information includes:
- ESC Temperature
- Total Current
The RCOU messages are also written to the onboard logs which hold the requested output level sent to the ESCs expressed as a number from 1000 (meaning stopped) to 2000 (meaning full output).
This information can also be viewed in real-time using a ground station. If using the Mission Planner go to the Flight Data screen’s status tab and look for esc1_rpm.
Sending ESC data to the GCS requires using MAVLink2. Please check the appropriate SERIALx_PROTOCOL parameter is 2 (where “x” is the serial port number used for the telemetry connection).
