IMG_8470The ARS-Shield is a board that can host an Arduino (i.e. UNO)?module adding the capability to interface with a rotor (DC or AC) It?s compatible with K3NG rotator controller?who provides the Open Code of his project at the web site: If you enjoy the homebrew and you want to design your own rotor controler this ARS-Shield will be a piece surely you will need and appreciate.


The ARS-Shield supports:

  • 5 relays (ccw, cw, aux, up, down)
  • LCD Display

  • Azimuth and Elevation optional ?Signal Conditioner? for rotors that don?t supply 0-5V on their output.

The ARS-Shield can be used with an Azimuth or Azimuth & Elevation rotors.


As an extra option, we can supply an aluminum case?which fits perfectly the ARS-Shield. A 16?2 characters Display and 4 buttons are included.

A signal conditioner PCB is also available for those rotors that supply a voltage feedback < 5V ?or > 5V. The design includes a Sallen-Key filter to avoid RFI. This PCB unit is?delivered assembled and tested.
