uSKY Frsky Nano Receiver

uSKY Frsky Nano Receiver


The uSky nano receiver is the worlds smallest and lightest FrSky compatible full telemetry receiver, measuring at just 11.2mm x 8.51mm and weighing 0.37g. This is from the designer of the TinyFish, Simon and is published as a uSKY open source project uSKY nano FrSky receiver of revolutionary tiny 11.2mm x 8.51mm size which weights only 0.37g will take your mini/micro FPV racing drone to the next level of miniaturization.

antenna length is correct = 31.5mm long (1/4 wavelength at 2.4GHz) 

NOTE: The signal cables comes to the "bind" pad. after your bound. Please change the wire to the PPM/SBus pad (see pictures)

For ease of use the RX will come with power and signal wires.  to bind connect the signal and ground wires 

  • 11x9mm at 0.4g so it's absolutely tiny and light.
  • Runs completely open source firmware (hardware is also open source)
  • SBUS output (only runs in D8 mode for now so not compatible with EU LBT firmware)
  • Runs at 3.3V (so watch out for this because most FC have 5V supply for ESC)
  • Specifications:
  • Voltage: 3.3V
  • Output: SBUS
  • Weight: 0.37g
  • Size: 11.2 x 8.51mm
  • Compatibility: Frsky D8 X9D Plus (installed and loaded)
