Description

The RadioLink R12DSE receiver provides a professional-grade link for pilots using compatible AT9, AT9S, AT10, and AT10II transmitters. Its hybrid dual spread spectrum (DSSS+FHSS) technology ensures a strong, interference-resistant connection, capable of maintaining control at distances up to 4,000 meters in open, ideal conditions. This makes it suitable for long-range FPV exploration and large-scale model aircraft.

Engineered for integration, the unit’s minimal 2.5-gram weight and 30x15mm profile allow for installation in the most space-constrained racing drone frames. The receiver is built to handle typical vibration and environmental stresses encountered in RC flight, especially when properly secured and protected. The selectable SBUS (digital serial) and PPM (pulse-position modulation) outputs offer flexibility for various flight controllers and servo configurations.

Key Features

  • Hybrid Spread Spectrum: DSSS and FHSS dual-mode operation enhances signal stability and resistance to interference in crowded 2.4GHz environments.
  • Dual Protocol Support: Switch between low-latency SBUS and universal PPM output modes via a simple button press, indicated by blue/purple or red LEDs.
  • High-Resolution Control: 4096-level resolution combined with 0.5µs signal precision delivers smooth, accurate control for servos and flight controllers.
  • Optimized Antenna Design: Features a detachable antenna, allowing for optimal 90-degree positioning to maximize signal polarization and range.
  • Low Power Operation: Functions on a standard 4.8-6V input (40-180mA current draw), compatible with most BECs and drone power systems.
  • Ruggedized Construction: Designed to withstand the vibrations and physical demands of high-performance drone and RC model use.

Applications

  • FPV racing and freestyle drones requiring a reliable, lightweight receiver for RadioLink transmitters.
  • Long-range fixed-wing and VTOL models where extended control range and signal stability are critical.
  • Micro and sub-250g drone builds where every gram and millimeter of space is optimized.
  • Scale RC aircraft and helicopters needing high-resolution, precise servo control with anti-shake capability.
  • Ground robotics and rover projects utilizing SBUS or PPM for control signal transmission.

Frequently Asked Questions

What RadioLink transmitters are compatible with the R12DSE receiver?

The R12DSE receiver is designed for use with RadioLink's AT9, AT9S, AT10, and AT10II 2.4GHz transmitters. It utilizes a proprietary hybrid DSSS/FHSS protocol, so it is not compatible with other brands like FrSky, FlySky, or ExpressLRS systems.

How do I switch between SBUS and PPM output on the R12DSE?

To switch protocols, quickly press the ID SET button on the receiver twice. The LED will indicate the active mode: a blue or purple light signifies SBUS output, while a red light indicates PPM output. Ensure the receiver is powered and connected during this process.

What is the maximum control range of the R12DSE receiver?

Under ideal, open conditions with a clear line of sight, the R12DSE can achieve a control range of up to 4,000 meters (approximately 4 km). Actual range will be significantly reduced by obstacles, interference, and improper antenna placement.

How should I install the detachable antenna for best performance?

For optimal signal reception, position the antenna so its active section is straight and at a 90-degree angle relative to the transmitter's antenna. Keep it away from carbon fiber, metal components, and battery packs to minimize signal blockage or reflection.

What voltage does the R12DSE receiver require?

The receiver operates on a voltage range of 4.8V to 6V DC, typical of most BEC outputs from ESCs or flight controllers. Its current draw ranges from 40mA to 180mA depending on the input voltage and operational load.
