The FrSky ADV FAS40 Current Sensor is part of FrSky's enhanced ADVANCE (ADV) series of telemetry sensors, designed to provide reliable current and voltage monitoring for RC aircraft power systems.

The FAS40 ADV Current Sensor measures electrical current up to 40A and supports battery voltages up to 6S when installed between the battery and ESC. This makes it a practical solution for monitoring the electrical system of a wide range of electric RC aircraft.

The sensor fully supports the FBUS protocol and is also compatible with S.Port, allowing it to connect to compatible FrSky receivers and provide useful power system telemetry. FBUS compatibility also helps simplify model builds and telemetry wiring.
