KiCad Design Files for DIY Construction and Evaluation

This relay interface allows a controller such as SatBox or the Fox Delta ST2 to control a Kenpro AC motor rotator. This page provides the schematic, PCB data, and KiCad library for download.

Download the design files / How to use the files

To purchase a bare PCB or an assembled board, please visit the Rotator Relay Interface sales page for prices, available options, and contact details.

How to Use the Downloaded Files

1. Save and extract both ZIP files: the Ver1.2 schematic and PCB data and the KiCad library ver6. Use separate working folders to avoid mixing them with older versions.
2. Open the extracted design files in KiCad and inspect both the schematic and PCB. Confirm that you are using Ver1.2.
3. If symbols or footprints cannot be found, check the location of the extracted libraries and your KiCad library settings. Specify file names and paths according to the extracted folder structure.
4. Before ordering boards, run the electrical rules check (ERC) on the schematic and the design rules check (DRC) on the PCB, and review the reported issues. Also check board dimensions, hole locations, connector orientation, and actual component dimensions.

Before Assembly and Connection

Operation has been tested with the Kenpro KR-400 and KR-500. For other models, check the motor drive voltage, terminal assignments, control method, and relay contact ratings.

The required power supply circuitry differs depending on whether you use the original potentiometer or replace it with an AS5600 magnetic encoder. Refer to the board description below and the related construction article to confirm the configuration you need.

Disconnect power before wiring. Check for short circuits, correct component polarity, and correct connector wiring before applying power. When testing with the rotator, verify the direction of rotation and stopping operation before use.
