Graupner telemetry


In stock

The MicroVario is a highly sensitive altimeter / variometer that uses components made with the latest MEMS technology for high accuracy while maintaining miniature dimensions. The sensor is able to detect slight changes in the atmospheric pressure and thus indicate the rate of increase / decrease.


  • Miniature dimensions - the sensor can be connected directly to the receiver's telemetry port
  • Power supply from receiver bus / telemetry (3.5-12 V)
  • Accurate measurement of absolute / relative altitude and climb / descend speed
  • Automatic telemetry detection: Futaba S.BUS2, Graupner HoTT, Multiplex MSB, JETI Duplex EX
  • Adjustable altitude and Varia alarm
  • Setting via the transmitter telemetry menu (Graupner HOTT and JETI only)
  • Updated firmware
  • Thanks to its miniature dimensions (as a servo connector), the MicroVario can be connected directly to the receiver's telemetry port or to any other suitable place in the model. It is compatible with Futaba S.BUS2, Graupner HoTT, Multiplex MSB and JETI Duplex EX telemetry systems. When using Futaba and Multiplex RC kits, the altitude and ascent / descent data are displayed on the fixed addresses of the sensors, while using the Graupner HoTT and JETI kits there is an extended menu that also allows you to set up MicroVaria directly on the transmitter.

MicroVaria configuration with JETIBOX:

After connecting to JETIBOX, you can view the current measured values (these parameters are also part of the extended menu for Graupner HoTT and JETI RC sets):

  • relative height
  • vario
  • absolute atmospheric pressure
  • temperature

Settings - parameters:

  • menu language (Czech, English, German, French, Italian)
  • sensitivity of the variometer
  • model decrease (to increase the sensitivity of thermal detection, it is possible to automatically read the value of the natural decrease in model performance)
  • atmospheric pressure at sea level
  • rounding the height to full meters
  • height warning (only for JETI and HoTT)
  • Varia warning signal (only for JETI and HoTT)

Technical data:

  • Pressure measurement range: 300 ÷ 1200hPa
  • Height resolution: 0.1 m
  • Telemetry: Futaba S.BUS2, Graupner HoTT, Multiplex MSB, JETI Duplex EX
  • Supply voltage: 3.5 - 12V
  • Working current: 15mA
  • Dimensions: 15 x 9 x 4 mm
  • Weight: 2g

The FOXY MicroVario is designed and manufactured in the Czech Republic.
