FrSky FAS150 ADV Current Sensor: 
 
FrSky ADVANCE (ADV) series has comprehensive sensor types and enhanced the performance and capability of the original sensor line, all ADV sensors fully support FBUS protocol and they are also S.Port compatible. With the FBUS protocol, the ADV sensors can be seamlessly paired with the FBUS-capable receiver and further simplifying the builds setup.
 
The FAS150 ADV current sensor can be used to measure current (maximum 150A), and the battery voltage (60V) can be measured by soldering to the voltage sensing pad of the mainboard. The mainboard also includes a temperature sensor interface to meet the user's needs for temperature data in specific applications.
 
 
Why We Recommend This
The FAS150 ADV is essential for turbine and large-scale electric aircraft — 150A max current measurement with precision FBUS telemetry means you're monitoring battery health and current draw live on your radio screen, protecting expensive power systems from overcurrent events. FPV Builds RC provides U.S.-based product support, sensor-selection assistance, and setup guidance for FrSky products purchased through our store.
Frequently Asked Questions:
 
What is the FrSky FAS150 ADV used for?
The FAS150 ADV is a high-current telemetry sensor designed for large-scale electric RC aircraft, gas turbine jets, and high-power electric models. It measures current up to 150A and battery voltage up to 60V (approximately 14S LiPo), streaming real-time power consumption data to your FrSky transmitter via FBUS or S.Port. It also includes a temperature sensor interface for monitoring motor or ESC heat in demanding applications.
 
FAS40 vs FAS100 vs FAS150 — which current sensor do I need?
Choose based on your peak current draw: the FAS40 ADV handles up to 40A and is ideal for small electrics and sport planes. The FAS100 ADV covers up to 100A and suits most medium-to-large electric aircraft. The FAS150 ADV is built for high-power turbine and large-scale electric models drawing over 100A.

Which FrSky receivers is the FAS150 ADV compatible with?
The FAS150 ADV works with any FrSky receiver that supports FBUS or S.Port — this covers the full TD Tandem, TW Twin, and Archer Plus receiver families. FBUS is the preferred connection for cleaner wiring. Browse compatible receivers at https://www.fpvbuildsrc.com/frsky-receivers.
 
How do I wire the FAS150 to my ESC and battery?
Install the FAS150 ADV in series between your battery pack positive lead and ESC input. The sensor's FBUS or S.Port wire connects to your receiver's corresponding port. For voltage monitoring above the current path, solder to the voltage sensing pads on the mainboard per the FAS150 wiring diagram in the FrSky documentation.
 
How does telemetry from the FAS150 display on my transmitter?
When paired via FBUS with a compatible FrSky receiver and a Tandem X18 or X20 series transmitter running ETHOS, current (amps), voltage (volts), and power (watts) appear as live telemetry widgets on your home screen. You can set audio alerts for low voltage or high current thresholds directly in ETHOS. S.Port connections display the same data on older ACCST-based radios.
 
Can the FAS150 ADV handle gas turbine jet applications?
Yes. The 150A current ceiling and 60V voltage range make it well-suited for turbine-powered jets where electric starters and ignition draw large current spikes. The temperature sensor interface also lets you monitor turbine or battery temperature as a second data channel, which is valuable for turbine health monitoring during flight.
 
Does the FAS150 ADV require any firmware updates?
ADV sensors communicate via FBUS and are automatically recognized by current FrSky receivers and ETHOS firmware without separate sensor firmware updates. Keep your receiver and transmitter on the latest ETHOS release to ensure all telemetry fields are displayed correctly.
