Description

This mini receiver delivers a full-featured control link in a package barely larger than a postage stamp. It utilizes GFSK modulation across 135 bands within the 2.4GHz spectrum, ensuring a stable and interference-resistant connection for your aircraft. The integrated SBUS support allows for high-channel-count setups with minimal wiring, simplifying flight controller integration.

Engineered for durability in tight spaces, the receiver’s low current draw of 40mA minimizes power system strain. Its -92 dBm sensitivity and optimized antenna provide a reliable control range exceeding 300 meters in typical flight conditions, making it a capable choice for both indoor micro drones and outdoor park flyers.

Key Features

  • Micro-sized form factor (20x14x5.3mm) for installation in the most space-constrained builds.
  • Dual-protocol output provides flexibility for PPM (8ch) or SBUS (up to 18ch) flight controller connections.
  • Broad 4.0-8.4V input voltage range supports direct power from 1S, 2S, or regulated BEC sources.
  • High-sensitivity (-92 dBm) RF front end with a 26mm antenna for robust signal acquisition and range.
  • Low 40mA operating current minimizes overall system power consumption.
  • Lightweight 1.2-gram construction helps preserve the agile flight characteristics of micro drones.

Applications

  • Ultra-lightweight 1S and 2S micro FPV racing drones and Whoops.
  • Compact park flyer and indoor RC airplane builds requiring a small receiver footprint.
  • DIY micro quadcopter and hexacopter projects where weight and space are critical constraints.
  • Backup or secondary receiver for bench testing FlySky-based drone control systems.

Frequently Asked Questions

Is this receiver compatible with my FlySky i6X or other FlySky transmitter?

Yes, this receiver is designed for FlySky's AFHDS 2A protocol, which is used by transmitters like the FlySky FS-i6, FS-i6X, FS-i6S, and other models bearing the AFHDS 2A label. Ensure your transmitter is bound to the AFHDS 2A mode, not the older AFHDS mode, for proper compatibility.

What is the difference between using the PPM and SBUS output?

PPM outputs a combined signal for up to 8 channels, requiring only one signal wire to your flight controller. SBUS is a digital serial protocol that can support up to 18 channels on a single wire, offers lower latency, and is the preferred method for modern flight controllers like Betaflight. You select the protocol by connecting either the blue (PPM) or white (SBUS) signal wire.

Can I power this receiver directly from a 1S LiPo battery?

Yes. The receiver's specified operating voltage range is 4.0V to 8.4V. A fully charged 1S LiPo provides 4.2V, which is within the acceptable range. For 1S builds, ensure your power wiring provides a clean 4.0V+ supply to the receiver's red (VCC) and black (GND) pins.

How do I connect this receiver to a flight controller like an F4 or F7 board?

Connect the receiver's black wire to a flight controller GND pad, the red wire to a 5V or VBAT pad (ensuring voltage is within 4.0-8.4V), and either the white (SBUS) or blue (PPM) wire to a dedicated SBUS_in or PPM input pad. You must then configure the corresponding serial port or receiver protocol in your flight controller firmware (Betaflight/INAV).
