Castle Link Live

Castle Link Live is a bidirectional communication protocol that gives the ESC the ability to transmit real-time telemetry feedback over the standard receiver cable. Crucial information like RPM, temperature, voltage, and current are only a fraction of the possible information that a Castle Link Live enabled ESC can provide. If you are an electronics hobbyist who would like feedback from your Castle ESC then check out the protocol datasheet posted below. If you would rather not decode the protocol yourself then check out some of the existing Castle products which are already set up to read Link Live data, such as the Castle Serial Link.
