Frequently Asked Questions:
What is the FrSky NFC Power Switch and how does it work?
The FrSky NFC Power Switch lets you power on and off your RC aircraft's receiver system without physically connecting or disconnecting the battery. Using NFC (Near Field Communication), a brief tap from your smartphone or an NFC card near the switch toggles the power state. This is particularly useful on aircraft with tight fuselages where accessing the battery switch or XT connector is difficult once the hatch is closed — you can arm and disarm without opening the model.
Which FrSky receivers is the NFC Power Switch compatible with?
The NFC Power Switch is compatible with FrSky receivers that have a standard power supply connection. It is designed to integrate into the power path between the battery/BEC and the receiver, acting as a controlled power interrupt. It is not receiver-specific and works with all TD Tandem, TW Twin, and Archer Plus FrSky receivers. Browse compatible receivers at https://www.fpvbuildsrc.com/frsky-receivers.
What is the power rating of the NFC Power Switch?
The NFC Power Switch is rated for the power loads typical of RC receiver systems. Exact voltage and current specifications are detailed in the FrSky NFC Power Switch documentation. Do not use it on the main motor power line — it is intended for the receiver and accessory power circuit only, not for high-current ESC connections.
How is the NFC Power Switch wired into my aircraft?
The NFC Power Switch kit includes the NFC switch unit and a Power I/O board. The switch installs in series on the power supply line between your BEC or battery and your receiver. The NFC antenna is positioned near the model's surface (under a thin covering or hatch) for reliable NFC activation. Refer to the FrSky NFC Power Switch wiring guide for connector and installation details.
What NFC device do I use to activate the switch?
Any smartphone with NFC capability (most modern Android and iPhone models) can activate the FrSky NFC Power Switch by tapping near the switch antenna location. A compatible NFC card supplied or specified by FrSky can also be used as a dedicated activation tool kept in your flight bag.
