FrSky TD SR12 Tandem Dual-Band Receiver (2.4GHz/900MHz)

Power-packed dual-band receiver with advanced stabilization and unparalleled signal reliability.

Overview
The FrSky TD SR12 Tandem receiver isn’t just another RC receiver—it’s a robust, dual-band powerhouse that operates on both 2.4GHz and 900MHz frequencies simultaneously. This means you get low-latency control with long-range resilience, no matter the interference. With a triple antenna design (2×2.4GHz & 1×900MHz), the TD SR12 ensures wide, multi-directional signal coverage for seamless communication with your radio.

Designed for RC enthusiasts who need dependable, long-range performance, this receiver takes things further with a dual-power system via XT30 connectors, allowing balanced consumption from two power sources. It also includes a socket for an NFC-compatible external switch panel, enabling easy use of the built-in power switch function.

The TD SR12 is a dream for custom builds, offering 12 fully configurable channel ports, each of which can be assigned as PWM, SBUS, FBUS, or S.Port. It’s compatible with various telemetry devices like Neuron ESCs and advanced sensors, simplifying your setup.

Advanced Stabilizer (ADV) Function
The SR12 isn’t just about signal strength—it also features an ADV Stabilizer function that improves on traditional gyroscopic stabilization. With five additional stabilization channels, it provides precision control across multiple flight modes like Stabilization, Auto-Level, Hover, and Knife-Edge, especially useful for fixed-wing airplane models.

The advanced stabilization mode allows for even greater control, with all output pins configurable for stabilization and extra features like file sharing and programmable parameters.
