Tech Notes:
Running modes: SMARTSENSET, Sensored, Sensorless with Castle sensored capable ESCs.Water Resistant Design: The sensor board is coated with silicone conformal coating to protect the sensors from moisture. The sensor connections are not water resistant: water can cause signal loss which could result in loss of sensored capabilities. Castle recommended applying dielectric grease to the outside of the sensor wire connections after installation of the wire. Routine maintenance is recommended after running in wet conditions. Please refer to this document for running and maintaining motors in wet environments.
